Problem With Small Primers in .45 ACP

Much of the. 45 ACP brass I pick up at the range is Win NT with a small pistol primer pocket. While I have not had any prolems with other cases with large pistol primer pockets, these small ones are difficult to seat. They protrude slightly, a few thousands, above the brass. I am using a Lee hand primer and have no problems seating both large pistol and large rifle primers.

I cleaned the pockets prior to priming and even ran them through the hand primer a second time to try and get then seated lower but this did not get all of them down. Everything I have read says not to use ammo when the primers protrude. I would say close to half the 100 cases I primed today suffer this problem.

Help!!!
 
You should try the Lee Auto-Prime II. It's a press-mounted version of the hand primer. It's good because you use your arm instead of your thumb to prime so your thumb doesn't get all sore and you can set the priming depth so it's consistent all the time. I found that sometimes I would tend to seat primers too deeply with the hand primer and would get bad firing pin strikes, but that's not a problem with the Auto-Prime II. I keep the Auto Prime die on a turret with my decapping die.
 
I just switch from using the large primer to small primer pockets (45acp)for convenience since most of the calibers Im loading are using the small prim. I never had a problem using the Win Nt brass.
 
Agree with HPL, have done several hundred 45 NT brass with win sprimer and lee ram prime(just like autoprime but one ata time). No problem, NO primer pocket crimp.
