45 ACP with small primers?

[Dalerj]

Just finished loading a batch of range pick up 45 ACP. While priming them, I came across some that had small pistol primer pockets. They were marked" WIN NT 45 AUTO".

Can you guys give me any info as to why they have small pistol primer pockets. Is there some advantage to the small pockets?

Just interested cause they were a pain in the @** but the major ammo mfgrs. usually have a good reason for doing things. What might that be?

Thanks, Dalerj

Environmentally clean primers.

NT means Non-Toxic. They use a "Dinol" priming compound instead of lead styphnate.
Dinol is a "hot" ignitor and it does not take as much as styphnate so they just use small primers. First generation Winclean used large primers but had large flashholes to vent the primer pressure buildup into the case.

If you have a bunch, they can be reloaded with standard small pistol primers at a reduction of 20-40 fps depending on the powder. Even though the makers would try to scare you out of using them if consulted.

If you only have a few, scrap them.

Note that Federal NT small primer cases are heavily crimped.

There are also some Blazer brass .45ACP that use the small primer. I try to cull them out when I'm sorting range brass pickups. I save them in a ziploc and will reload a box full when I have enough brass.

They are a PIA if you don't notice them.

Small pistol primers also for cases marked "FIOCCHI USA 45 A.C.P."

Do a search on here. There are many threads dealing with .45 ACP cases with small primer pockets.

Load'em...Shoot'em...Load'em again. They work just fine.
