Marshall, I bought your book and lapping slugs and, well.. it sure worked as you said it would! Got my goups a lot smaller and velocity is up too. I can't believe this rifle...giving me cloverleaf groups at 100 yds with 300 gr LBT slugs after lapping it. Now when are you going to finish the .444 Marlin Part IV article? I filed the other 3 as good resource. I can't wait for the last part.
Thanks, you folks are great!
