One thing I thought about this, is the smaller base would have the round chambering deeper into battery. The issue is light hammer strikes, so I would think it would be worse if primer farther away.

I do remember one time, not slamming it home, when going to my stand in the morning trying to be quite. It didn't go off. But in that case, I remember the trigger didn't even fire. But that was over 20 years ago.

Hunting season now, will work on it later. I'll report if I find anything to help who ever may discover this on google in the years to come. If they make to page 12.

I did try measuring primer pockets, maybe .001 deeper, I was doing it quick, so not most accuarte, with end of calibers. Dial indicator in jig would be the way to go, same with he head space gauge.
