i usually load winchester 45 acp brass exclusivly. a friend gave me some of his once fired federal brass. during the priming process the feds would not accept a large pistol primer. when i looked at the pockets i saw that the fed. brass took small primers. is that normal or was it a messed up lot.

It is normal. Every day it is becoming more and more common for the 45ACP to be loaded with small pistol primers, as it is not necessary for a cartridge that uses such small charge weights to utilize large pistol primers.

Typically found on "Non-Toxic" rounds.

I suppose it is normal although I don't have much Federal brass mostly just winchester and remington.

As others have posted, those are normal. It's an extra step you must go through with 45ACP - sort cases by primer size. It's a nuisance if you miss some in your batch of large primer cases when running them through a progressive press set-up.

As was pointed out,those are found on the NT type ammo which are loaded to be non-toxic (lead)
Some folks have told me that the smaller primers have less "brisance" and so, ignite the powder "more gently". Supposedly the loads are then more consistent and more accurate. I dunno, I think I would need to use a machine rest in order to test that theory but I doubt that would change much for me. Still, no problem with using the cases as long as you don't try to stuff a large primer into a small hole.

They are definitely a pain in the backside. Very annoying at the least.

Federal and CCI have been using small primers in .45acp brass for a while now.
