Six Pack Pro question- for those that are currently using one

[BrianT]

Fyodor, I shoot a lot of different ARs, and don't feel comfortable with flush primers, due to the floating firing pin. Sometimes, not often, you can just let the gun go into battery, eject the round, and see a small spot where the firing pin hit the primer.

May I ask why you are not satisfied with flush primers?

While sorting my fresh loads into boxes, I check each and every primer with my finger to be at least flush. But they are considered good when flush, too. Just not protruding. I never had any problems with rounds not going off. Most of my guns are revolvers and lever rifles, but I also have two 1911s. The cowboy guns have drastically reduced main springs. All go off on the first strike, with the primer flush or seated deeply.

Is there anything I didn't see? Why is just flush not considered sufficient?

Same here. And I never trim pistol brass either.

I have had "slamFires" in my AR's when I first started loading them, I was buying all Federal primers then. A friend advised to switch to a "harder" primer, and gave me some CCI's, at the next CMP match I had no surprises!

@BrianT:
I don't think a few thousands would make much of a difference.

I do exactly as you do, run my fingers across the tops to make sure none are protruding. You can't really "feel" a 2 thousandth seating depth but I'll bet if you measure them as you seat your primers you'll find most all of them will be 2 or more thousandth deep. Perceived safety perhaps, but I've also read that primer seating depth should be from 2 thou all the way up to 8. A lot of information and opinions on that amount though. That pertains mostly to rifle reloading that I've read about. It can be a "hot" topic debate for sure. But that's just my preference and like you I've not had any misfires due to a flush primer If in fact I had primers that were "flush" seated because I don't check them all for sure. The 45acp rounds I did find that were just flush (0.00) probably would have fired just fine but the "perceived safety" with an auto loader reared it's ugly head for me.
