Just started the barrel break in this morning, this will not take long. Only three rounds down the tube and there simply is no copper fouling to mention after a few strokes with a bronze brush and some butches bore shine.
The load I am using is 145 gr of H-50BMG under the 300 gr SMK seated 50 thou off the lands and lit with a Fed-215 primer.
Average velocity has been 3455 fps for those three shots. This load is a full 5 grains under my set max load so I would guess 3500 fps will not be much of a problem.
Just another tid bit.

Acually I would love to hear how you have been assembling your ammo. I would agree w/ you Kirby about the Dave posting. I have not posted much on this site but I love to see and read what you and GG have been doing lately. Please keep us posted, I have a change in rifles coming up and would like you to do the work. Again Thank you for your dedication.
