Ah. Thank you. I'd known for a while that the thicker-cup primers were "better" for that reason. Been very lucky up to now, I guess. I've never had an issue with regular primers in my 5.56 loads. Loaded and fired 1000-1500 or so over the years. Not a huge test size I know. I had one double-fire event, about 20 years ago. Factory ammo though, I think. Most of my 5.56 loads have been with Winchester SR. And I have these CCI 400s that I got somewhat recently. I'll have to use those up on 5.56 and hope for the best, that my lucks holds out with them.
I do have the Rem 7.5s and CCI #41s on hand. For Grendel I'll stick with those going forward.
Does anyone know, is it dangerous to press out live primers using a decapping die? And would it ruin the primers? I figure that last one might be a dumb question. Probably crushes the anvil a little, at the very least. In the old days I wouldn't have cared too much. But damn, the price of primers these days makes me want to cry. Price sticker still on my box of #400s says #39.95. I think they've more than doubled by now.
Edit: I was thinking impulsively above. Those 50 CCIs cost me $2. About $4 at todays prices. Obviously not worth caring about too much. Cheap lesson I guess. I could just write these off and push in #41 primers. Or keep the #400s in the these cases and just go with a light load, winch would help with pressure at least, but doesn't do anything for avoiding slam-fires. Hmm.
