It's like lots of things, there are ways around a problem. Proper solution is to have a small fireing pin that doesn't have much slop in it. If you don't have that, then another solution is to use primers with thicker cups, that will work also and is a perfectly fine solution to the problem. A factory has to produce a rifle that will be good with anyones factory ammo, but you are not so constrained. Larry
P.S. I did find the ATF transfer laws printed on ATF Stationary about transfer from a nonlisensee to a lisensee, however I am kind of afraid to post it for fear of being forever banned. Larry
