Part III
Heavy Bullets & Loads In The Triple-Four
Previously in this series: The .444 Marlin- America's Most
Versatile Big-Bore, we have examined the historical background of the
cartridge and it's rifles, and explored the dimensional characteristics of those
firearms, and the unique requirements necessary to extract top performance from
these guns.
In this segment, our focus shifts specifically to development of
heavy bullet loads for the .444 Marlin. The emphasis here is on bullets
over 300 grains in weight, and their application in this most interesting and
versatile big-bore cartridge. In previous years, prestigious publications
have explained the absolute uselessness of bullets over about 290 grains in the
.444 Marlin, and have gone so far as proclaim that the 1:38" twist of the
Micro-Groove barrels positively won't stabilize bullets over 310 grains in
weight. The data presented here speaks for itself, and necessitates no
defense, the resultant tests revealed some startling surprises and insightful
observations.
As described in Part II, both test rifles are equipped with
scopes for the purposes of load testing, barrels have been fire-lapped and
polished and the triggers on both tuned to break crisply at near three pounds
pressure. All test groups were fired on the Beartooth Bullets Shop Range
off of a covered bench rest and sandbags at 100 measured yards. All
shooting temperatures were recorded at the time of testing and are noted in the
data. Too, all shooting was accomplished over a period of several day's
range sessions, waiting for zero wind conditions. Loads were chronographed
utilizing a Chrony, Alpha model chronograph set up fifteen measured feet from
the forward edge of the shooting bench, and listed velocities are a composite of
two separate and distinct series of shots using the same load, then the averages
of the two series reported. Those group sizes reported are measured center
to center using a stainless steel dial caliper, and in those cases where there
was an obvious flyer, the reported group is a measurement of the remaining
clustered shots, but in no case was more than one shot factored out for any
reason.
A quick note about the group sizes and accuracy of these
big-bore lever action rifles. The .444 Marlin is a heavy hitter in all
respects, and develops some severe recoil with these heavy loads. In light
of the extreme number of test rounds fired through these guns for this article,
we employed the use of a twenty-five pound bag of lead shot positioned between
the but of the rifle and the shooter's shoulder. This, in an effort to
report the true accuracy potential of a given load rather than try to quantify
the flinch coefficient of the shooter!
It is interesting the potential accuracy of these .444 Marlin
rifles. No, they aren't benchrest guns, nor are they anything that has
been accurized through glass bedding, or other bench rest shooting
accurizing techniques. In examining the group sizes reported through
these tests, please bear in mind the intended purpose for these guns and their
loads in regard to accuracy, and the suitability of a given bullet and load
combination in actual field hunting scenarios. It's interesting in looking
back over the writings of some of our more seasoned and respected shooting
sages, that I find this quote by Ken Waters in his January 1979 "Pet
Loads" write-up of the .375 Winchester model 94 Big-Bore concerning hunting
accuracy and reasonable expectations from these types of firearms:
"What sort of accuracy am I talking about here? Well,
with a light hunting rifle such as this with its short sight radius, I look for
loads that will put five successive shots in four inches at one hundred yards
using the issue open sights, or three and a half inches with a receiver-mounted
peep sight."
Once the barrels are lapped and conditioned, and fed the right
combination of bullets and powder, these .444's far exceed such mediocre
expectations from a hunting carbine! In fact, these Marlin lever actions
with the proper load combinations behave much like a well tuned target
rifle! It is rather like engineering pinpoint accuracy when directing a
locomotive's impact.
Now, for the bullets. As we explored in Part II these .444
Marlins thrive on .432" diameter bullets, delivering their tightest
accuracy and best ballistic uniformity with bullets of this dimension. For
the purposes of this segment, all bullets tested are BHN 21, as all we are
interested in at this point is high-velocity and heavy weight projectiles.
All bullets employed in these tests were used with our newly developed blue
lube, and are of gas-checked design. The photograph below illustrates all
of the gas-checked bullets available from Beartooth Bullets employed in tests
for this series of articles on the .444 Marlin.
Powders best suited to the heavier weight bullets in the
Triple-Four are those in the Medium to Medium-Fast burning rates. For the
heavy bullet testing for Part III of these articles, we used the following
commercial canister powders: Hodgdon Varget, Hodgdon H332, Hodgdon H335,
Alliant RL-7, Accurate AA 2015 and IMR 3031. Although there are a number
of other powders that fit within this burning rate range, the powders listed
were selected by merit of their performance specifically with heavy bullets in
the .444 Marlin. Performance criteria included ballistic uniformity,
accuracy, pressure vs. velocity, muzzle flash and uniformity of performance over
temperature extremes.
Reloading equipment for these tests were basics: RCBS
Rockchucker press, Lee Auto-Prime priming tool, Pact Digital powder/bullet
scale, Forster case trimmer, MTM case loading blocks, Midway case
deburring tool, RCBS primer pocket uniformer, RCBS flash-hole deburring
tool, reloading dies from Redding, RCBS, Lee and Hornady, micrometer from
Central Tools and a Sterret dial caliper.
As a side interest during this test, we ran accuracy tests
employing three brands of reloading dies, and one time-proven accuracy load,
with the intention of beginning another Tech Note, detailing the accuracy
differences incurred simply by employing different reloading dies. The
surprising, and great news is this: there was absolutely zero measurable
difference in the accuracy, either at the range, or in measured run-out of
loaded ammo, between the ammunition loaded with the various manufacturer's
dies! This is a real testimony to the exceptionally high quality standards
of manufacturing our shooting and handloading equipment manufacturers adhere to
in all phases of production.
In handloading for the .444 Marlin, a firm, well placed crimp is
essential for this high-energy, stout recoiling cartridge! Interestingly,
there are very few bullets that have crimping grooves or cannelures properly
placed for crimping when loading for the Triple-Four. In Beartooth's
line-up, there is only one bullet with an appropriate crimp groove for the .444
Marlin, and that is the 44-405g WLNGC bullet. However, there is a simple,
expedient and highly efficient cure to what might be viewed as a stumbling block
to the handloader of the .444 Marlin. That answer lies in the Lee Factory
Crimp Die! It is a truly excellent tool for this purpose. The Lee
die allows positive crimping where there is no crimp groove present, both on
cast and jacketed bullets. For the .444 handloader, this die is an
absolute MUST have item to open the doors of load diversity and bullet
selection.
It operates on a compressed-collet type system in which four
fingers of a collet are firmly, and positively pressed against the case mouth,
against the bullet, thus either making a very positive crimp in an existing
crimping groove, or literally creating its own crimp groove by the ingenious
design of the die's fingers being compressed, as seen in the photo below.
These bullets are both .432"-290g LFNGC's, the one on the left is as
manufactured by Beartooth Bullets. The bullet on the right is the same
bullet, after having been crimped into a .444 Marlin case using the Lee Factory
Crimp Die, and then pulled with an inertia-type bullet puller to illustrate the
"crimp groove" created by the factory crimp die.
Throughout the range of testing done for this series, scores of
loads have been tested both with a simple roll crimp tucked over the front of
the ogive of the bullet, and the exact same load utilizing the Lee Factory
Crimp, and in each and every instance, those loads employing the factory crimp
have grouped significantly smaller on paper, and recorded notably smaller
extreme spreads and standard deviation results over the chronograph.
Presumably due to the more uniform start pressure of the factory crimped
loads. In any case, the .444 Marlin necessitates a firm crimp both to
prevent bullets from moving in the tubular magazine during intense recoil, and
for uniform start pressures to enhance ballistic performance.
Bullet seating depth is another issue of great and far reaching
concern in this particular cartridge. Not only is the maximum cartridge
overall length (C.O.L.) limited by the action of the Marlin and Winchester
actions, and what will feed through cycling the lever actions, the throat length
in the chamber also plays a vital role in limiting the maximum C.O.L., as these
guns have relatively short throats, and those bullets with strong front driving
bands may require deeper seating than simply making the C.O.L. determination by
the actions cyclic abilities. Two such bullets are the LFN and WFN
profiles that Beartooth markets. Ideally you want to seat the bullets such
that when chambered, there is slight felt resistance as the lever is closed the
last eighth of an inch or so, and that the rifling in the throat actually
engraves the bullet to a slight degree. By no means should the bullet be
seated out such that it is difficult to extract a loaded round due to the
rifling being so heavily engraved on the bullet upon chambering. There is
a fine balance here, but the ideal seating depth for both these profiles is a
point where noticeable rifling engagement may be viewed on the bullet when an
unfired loaded round is extracted from the chamber as seen below.
,
Notice the factory crimp applied to both these loaded
cartridges. It is firm and positive, while insuring against bullet setback
in the case during recoil in the tubular magazine, it also provides excellent
uniformity of start pressure. When using the factory crimp die, there is
no chance of a bulged or collapsed case in the crimping operation, as opposed to
using the standard roll-type crimp feature built into all other .444 Marlin
seating dies.
Now, having explained the criteria for determining optimum
seating depth for the LFN and WFN profile bullets in the .444 Marlin, we'll look
at specifics lengths employed by the two test rifles for development of the data
presented. Although the .444S (22" Micro-Groove) barrel has a throat
that is 0.100" longer than that of the 444P "Outfitter"
(18.5" Ballard Cut-Rifled) barrel, all bullets for this series of tests
were seated to the same depth for each firearm and those dimensions are listed
below.

Keep in mind that the C.O.L.'s listed above were appropriate for
the two test rifles, the only way to insure that your individual rifle will
feed, function and perform properly is to adjust the C.O.L. accordingly to your
specific rifle. While these dimensions listed represent loading lengths
which function, feed and eject well from several .444 Marlin firearms, specific
tuning and tailoring may be necessary for individual rifles.

The series of tests resulting in the above data are the
compilation of enormous numbers of man-hours in both bullet production and
load development and assembly, culminating in this information after firing
under very controlled conditions and tabulation, then recalculation of
data. All results listed above may be readily reproduced by the individual
user of this data. All hard-copy targets and load data sheets are on hand
for verification of results and confirmation of validity.
Keep in mind, that the data supplied here in this table was
entirely safe for the guns in which it was developed, and in no case were the
loads listed here absolutely maximum in our test firearms. Too, none of
these loads were specifically "fine tuned" for either test
rifle. These test loads are representations of normal working pressure
ranges for the bullet and powder combinations listed, and as such are intended
only as an informational platform from which to develop loads for your
individual rifle. We were totally shocked by the accuracy delivered by
many of the loads in the accompanying table.
Unlike some previous data released by Beartooth Bullets, all
these tests were conducted primarily between 65 degrees and 80 degrees
fahrenheit. By performing load development at this temperature range,
results reflect more closely the average temperatures the majority of
handloaders will experience when performing load work-ups. Be advised that
the data developed in this temperature range greatly differs from some of that
data developed and reported in below freezing temperatures.
When loading the ammunition resulting in the above data, all
bullets used were of current production Beartooth Bullets products, as run, from
normal off-the-shelf stock. In no instance were bullets hand picked,
sorted, weight segregated or otherwise culled prior to testing. The
results presented represent actual shooting performance of the listed loads,
using bullets of normal production runs as they are customarily shipped to our
clients
Brass for these loads was from a single lot of bulk brass,
purchased specifically for developing the loads listed. Primer pockets
were uniformed, flash-holes deburred and cases trimmed to 2.215" then
lightly deburred inside and out. All brass was trimmed after every loading
(although not really necessary as it stretched little or any) just to assure
uniformity. Brass was not weight segregated however, but used at random as
it came from the distributor in bulk form.
Powder charges for all loads used in testing and development of
the accompanying data were each hand weighed on a Pact digital powder
scale. In no case were charges thrown by a powder measure, without being
weighed on the digital scale, and the last few tenths of a grain trickled in by
hand to "top off" each load. All powders loaded in these tests
were from single production lots within each brand and type of powder used.
Primers were all Winchester Large Rifle Primers, for standard or
magnum rifle loads. All test charges were loaded with primers from lot #
CHL168G943. There was no variance of primer manufacturer or type
throughout the range of tests, although it is entirely possible that by altering
primers in some loads, results may have changed dramatically. This set of
tests did not encompass the variables introduced by changing primer types and
manufacturers. Past experience and reams of previous loading data
concurred that ballistic uniformity tended to be at its best when the .444 is
loaded with these Winchester primers, so rather than introduce yet another
variable, we concentrated on bullets and powder selection.
As this data was developed, many unexpected results
emerged. The first surprise being that the short ported barrel of the
.444P model rifle seemed to deliver more uniform extreme spreads and standard
deviation results, across a broad spectrum of bullet and powder combinations
when compared to the longer barreled 444S with it's 22" tube. Another
pleasant surprise was the small loss of velocity in the 18.5" ported barrel
when compared to the 22" barreled version, all other factors being equal.
The individuality of these two rifles is quite evident in
examining the resultant data from our tests. There are several instances
where one rifle or the other will shoot sub MOA groups with a load, and its
counterpart developed a severe dislike for the same load. Another
interesting note, is that most of the loads tested indicated tighter accuracy
overall as loading pressures neared the upper end of the pressure envelope,
although there were exceptions to that observation, still the prevailing trend
indicated tighter groups at the higher end of the pressure spectrum.
Interesting too, is the difference in performance between the
two test guns with different weight bullets and changes in powders and
charges. The .444P "Outfitter" model with its 18.5" ported,
Ballard-Style cut rifled barrel, digested just about every load with acceptable
hunting accuracy. Sure, some loads I certainly would work upon in the
accuracy department, but nearly every load tested would bring home venison if
shots were kept under 150 yards. However, its real shining attribute is
this: its point of impact never changed more than three and a half inches
at 100 yards throughout the range of bullets, powders and velocities tested
throughout this investigation! Too, those changes were solely in
elevation! Never, with all the different powders, charges, bullets and
velocity ranges encountered, did the point of impact shift to the left or right
more than three-quarter's of an inch! A complete comparison of this
phenomenon including sub-three-hundred grain bullets will appear in Part IV of
this series.
Conversely, the .444S with its 22" Micro-Groove barrel was
extremely load sensitive. Not only did loads shift as much as eight inches
vertically with changes in velocity and bullet weights, but shifts of up to
seven inches in horizontal dispersion in point of impact was experienced with
changes in powder and bullet weights as well. The 444S is VERY picky about
the loads that it will shoot to the same point of impact with one point of
aim! Although the point of impact changed dramatically with several loads,
many of those loads still shot sub MOA groups, just not anywhere near point of
aim! The reasons for such a difference between the performance of the two
rifles we don't pretend to understand, instead we just report what we've found.
Recoil from these heavy loads when fired through the 444S
22" barreled version can be described as nothing short of fearful and
extreme! These high intensity loads put new meaning to recoil. The
fore-end of the rifle typically rose between three and five inches off of the
front sandbags when firing the 325 grain plus loads. Without added
shoulder protection when shooting from a bench-rest a shoulder is sure to
receive a colorful albeit painful change in coloration. The integral
Marlin Porting on the 444P "Outfitter" model with its 18.5"
ported barrel is a whole different critter. This gun, even with the
stoutest of loads only rises less than an inch off of the front sandbags upon
recoil. The sensation of recoil is different as well, being more a
concentrated push, rather than an excruciating jab.
Both guns stabilized all bullet weights equally at the
velocities represented in the accompanying data table. In no case was
there ever a bullet that failed to deliver acceptable to superb accuracy in both
guns except for the 44-405g WLNGC. Most times this accuracy level was achieved
with differing powder charges and or powder selections, but none the less, no
bullet performed to a less than acceptable level... for the exception of the
.44-405g WLNGC bullet. This particular bullet stabilized just fine at all
tested velocities in the 444P "Outfitter" model with its 1:20"
rifling twist; however, in the 444S model with it's 22" Micro-Groove
1:38" twist barrel failed to stabilize the 405g WLNGC bullet at all
velocities that were developed within uniform safe operating pressures. At
velocities under 1950 fps. this long bullet tumbled and keyholed in the .444S's
1:38" twist barrel in every instance. However, once velocities
exceeded the 1950 fps. threshold, the bullet remained stabile out past 100
yards, in order to generate these velocities pressures exceeded the limits of
safe and sane operation for the .444 Marlin in these guns, and that data will
not under any circumstances be made available. The 444P
"Outfitter" model with 1:20" twist in its 18.5" ported
barrel stabilized the bullet very well, and it remained so out to a distance of
over 200 yards!
For a rifle conceived as a short-range brush buster with 240-265
grain pistol bullets, this .444 Marlin cartridge certainly thrives on long,
heavy bullets, and does so with target-rifle type accuracy to boot! I
think it safe to say that the notion of .444 Marlin rifles not being capable of
stabilizing any bullets over 310 grains, not being able to shoot cast bullets
over 1600 fps. and being capable of "gallon jug" accuracy at a hundred
yards can all be definitively and finally put to rest as mythology! For
the woods wise hunter who limits himself to 200 yard shots at big game, this
.444 Marlin cartridge, loaded with any of the above listed bullets is MORE than
capable of harvesting anything in North America cleanly and decisively.
The first time, every time, with properly placed shots.
In examining the tabulated results of this extended
investigation, I note two particular loads that gave good to exceptional
performance in both rifles, and are outstanding loads for anything that walks on
the North American continent (and most in Africa if put to the test).
First is my tried and true, all time most used game load:
.432"-330g LFNGCDCG/56.0g H335/WLRP/Rem Brass/2.582"
C.O.L
Second place winner would have to be this load:
.432"-325g LCMNGC/50.0g AA2015/WLRP/Rem Brass/2.570"
C.O.L.
In the beginning of this segment of our look at the .444 Marlin,
we detailed the preparation of these guns for the tests to be run, in terms of
lapping and polishing the bores. Most gun-scribes and loading
manuals decry the propensity for leading in these fine guns. Just for the
sake of argument, all these tests conducted to compile the data for Part III of
this series, the heavy bullet/high velocity load development phase of shooting
was done WITHOUT EVER CLEANING THE BORE ONCE TESTING BEGAN!!! That's
right, NOT ONCE did we even touch the inside of the bores of these guns with
anything other than the bullets being fired! On a couple of occasions
there was a light gray wash in the bore, but never a lead build-up, and never
did the accuracy potential of either of the test guns deteriorate in any way
from leading or lead deposits! This was done purposefully, not as a stunt,
but to once and for all lay aside the notion that these guns won't handle high
velocity cast bullets without woeful inaccuracy, or resultant leading requiring
extreme measures and hours of cleaning to remove. Yes, another
misconception relegated to the mythology books! Just for the record, yes,
now that the shooting for this segment has been completed, each gun received a
couple of tight fitting patches on a jag, and saturated with Ed's Red, then dry
patched two passes with plain dry patches. They are both clean as a
hound's tooth!
Sure, we all know that there are tons of venison harvested
annually with much less gun than the .444 Marlin. After all, there's only
so much penetration and killing necessary on a skinny little whitetail
deer! However, there's something very reassuring and special when heading
afield with the confidence KNOWING that you can take ANY animal offered, in ANY
situation, from ANY angle with complete and total knowledge that when you pull
the trigger, the game's over! Also a satisfaction knowing that regardless
of the tough angles, that you have both the power and precision bullet placement
at your disposal for a clean, one shot kill on any game you hunt in North
America. Those of us afield in places where grizzly and moose are
commonplace appreciate that reassuring knowledge that our rifle has more than
enough potential for any situation that may occur. Big heavy bullets with wide,
flat meplats dictate consistently deep penetration, large wound channels and
guaranteed exit wounds. The familiar 336 Marlin or 94 Winchester platform for
these guns insures quick handling, instinctive shooting and intuitive
pointability. Couple these proven handling characteristics with
outstanding knock-down power and accuracy, and you've got the recipe for years
of satisfying and successful hunting success.
In summation, I would add that once loaded with bullets over 300
grains, the .444 Marlin begins to shine brightly as a superb big game
rifle. Loaded with any of these loads, it would be a most welcomed camp
companion when traveling in grizzly or moose territory, and gives up little in
terms of stopping power or penetration to either the .45-70 Govt. or the new
Marlin .450M. The accuracy potential of this gun over a wide variety of
both bullet weights and nose designs lends it to remain America's Most Versatile
Big-Bore!
Part IV will focus on loads utilizing cast, gas-checked bullets
from 250-300 grains, their loads, powders, applications and performance.
