Re: 208 Amax\'s and tight bores do not mix
Hard to dismiss the results, no doubt, and I'm not trying to argue the fact. I'm arguin, but mostly with myself, hahah, just trying to get my head around it all. While at HS, we shot every rifle for group. I have seen lapping take many a barrel which shot 5/8-3/4" @ 100, to 1/4" and less, but I never figured opening the bore up made the difference. Usually the difference was the bullet was exiting the muzzle more cleanly, as there were so slight of imperfections at the break from muzzle due to dull or misaligned tooling during the crowning process. A guy could 'feel' what was affecting the exit of the bullet, even ever so slight, in the additional lapping session. When the obstruction was cleared, went back downstairs for group, and it performed as it should have.
