Different size primer pockets

[Mr_Vism]

I'm reloading .45 ACP and I'm running into cases that I cannot prime because the primers are too big. Why do some of my cases have smaller primer pockets than others even though they are from the same box, and what can I do about it?

Could these be military brass with primer crimps? If so you may have to remove the crimp before repriming.

 

[Mr_Vism]

No, they're just your average Federal cases. The primer pockets are smaller in three out of the fifty I have from that box.

If the headstamp reads "NT" then they are small pistol primers. Thats your problem.

NT stands for Non toxic.

ICC and winclean use small pistol primers in 45acp. I did have a differance in where the bullets were hitting when I started reloading using the small pistol brass, so I have to stick to using either one or other brass and not interchange my rounds. The winclean small pistol brass seems to have a brass collars around the charge hole, so the primers don't seat the same with each round and the soft Federal primers get damaged sometimes.

I also noticed that Winchester .45 brass seems to be thicker than all of the other manufacturs I've tried and are a pain to load new or used brass, compared to my Federal or ICC brass. Anybody else have the same problems with Winchester brass?

Throw them out .... get on with your life.

Done and done.

Now I know what to look for next time, thanks guys; Don't take NT brass.
