Light Primer Strikes/ Hard Primers

[Johnny]

Does anyone have any problems with primer misfires on CCI large pistol primers. I have loaded a lot of them in some 45 acp. About one out of every mag misfires. I can throw the misfires in my buddies TRP and they fire fine. The misfires occur in an older P220. Anyone have an opinion on the culprit. Let me know if there is any other information I can provide. Or anything I can try and sort this out.

P220's need new hammer springs from time to time, mfg suggests every 2000 rounds it gets new springs.
You can get them directly from Wolf Springs by ordering on line. Not to hard to install yourself.

Thanks Honey bee. I will order one up.

CCI is what I use in Competition, and hunting. Never had a FTF, about 3K rounds through the Kimber stainless target II.

Good call but not a fair comparison IMO. The main spring in you Kimber is good for a vastly higher round count than 3k.

Thanks Duckhunter, but I don't trust google like I trust OSA. Welcome to the board.

Excuse me for asking, but are you ABSOLUTELY certain that you are seating them all the way. I loaded several thousand rounds of 9 mil, using a lee progressive, but sizing them first, and then priming with a lee hand primer. Some of my 9s woud fire them, and some wouln't (intermittently). Evidently the primer shaft was a hair short, in that particular hand primer. Wound up redoing them all, which cured it. Probably not your problem, but something to check, also embarrassing, as I have reloaded for years.

I didn't think to check while I put them in the mag but I checked them after the misfire. They were flush. I also did not put them back in the sig to try them a second time. My buddy just put them in his springfield and they fired. I forgot my wallet this morning so I will have to order the springs tomorrow. So between now and the time it comes in I will try a few more mags and will check the primer seating before I ding them. Thanks for the input.
