I scrounge all my 45acp brass and just recently loaded approx 325 rounds. This afternoon, I decided to load the balance of some 45 bullets just to get them off my bench. De-capped 15 brass and expanded mouth. during priming, two cases wouldn't accept the LP primers. discovered the 2 brass SPEER headstamp had small primer pockets. Other SPEER brass in the bunch I was using had the large primer pockets. Anyone out there know the story about this wierd stuff ?

Several manufacturers including Speer came out with ammunition loaded with lead-free primers in the last few years. Small primers stamps with NT (non toxic) were used to distinguish this ammo from standard ammo. What you have is probably once-fired factory NT .45 ACP cases.
 
I'll bet you have brass from frangible ammo, used for indoor ranges- like John Traveler says, the primers were meant to be lead free.
I've reloaded these in small batches with absolutely no problems...and no velocity difference. The GAP rounds are the same way.
 
It MAY not be .45 ACP. I believe .45 GAP uses small primers.
 
45 ACP brass, small primer

No, its 45 ACP not 45 GAP, that's why i was so surprised, been loading for40+yrs and never seen this stuff.

I have a lot of 45 acp brass with the small primer pockets and like so many others I just weed them out into the recyle bucket.

I'm seeing the NT stuff more and more and it is becoming a significant aggravation. The idea of going back to sorting cases does not appeal to me, but neither does the ruined primers from those cases.

At present, I check the case just before feeding it into the Dillon. Still slows the process significantly. Glad that GAP crap never caught on near me.
 
Here is what that .45 ACP-NT bad boy stuff looks like.

I got a shopping bag full of 45acp brass from the guy who cleans the range. After cleaning it I started to reload.

I had to stop and go through all of it, one by one. I couldn't believe how many different names were on the small primer brass.

Chuck 'em. Reloading safety issue here if you're runnung that progressive and unknowingly try to stuff a large primer into that small hole. One of the risks of picking up range brass, along with "Glock Bulged" brass in the high pressure calibers like 9mm, 10 mm, .40 S&W, etc.
 
Why throw them out? Some very generous members just sent me some as I ran out of large primers but had more small pistol primers.

Keep them separate just in "case" Never know what will happen in the future with primers.
 
I had a large primer go off in a progressive becaus of the "NT" brass, did'nt damage anything, BUT MAN it wakes you up.

Thats why I crush em, and toss in the recycle bucket. If you reload them, eventually one will make it into your regular .45 brass. I just hope you catch it if it does, I've heard of some progressives lighting off all the primers when one goes off.
 
Ran into a few of these in .38 the other day. Had small primer pockets with a crimp. Had to ream the pockets and then all was well. One of them would not let me fully seat a primer after reaming. Pitched that one.
