....brass. Federal train&defend .45acp uses SMALL primers instead of large like JMB intended. Instead of swapping over primers I used the 550B like an advanced single stage since it has manual indexing and 46 pieces was all I found (Ed the brass hawk will find those other 4 he's the brassfinder supreme.) I did cut back to a start charge of HP38 in these just in case.

WTF?

Never heard such nonsense!

JMB rolling in his grave.

Hey loading single stage I doesn't bother me to have some small pistol primers especially in today's primer climate.but it does suck opening an order of 45 ammo to find it has small pistol primers.lol
I'm thinking yuck this sucks lol but it's all good except sorting them bastages different
No biggie for me
I bet we'll see more and more now that large pistol primers are tough to come by

Some brands have been doing that for a while. If buying online, need to verify before buying. Most gunbroker listings will say either large primer or small primer in description.

Small pistol primer 45ACP brass is one of life’s little aggravations, for sure. Whoever came up with that should be whipped with a rubber hose.

After whipping them with a rubber hose, chunk all of those small primer 45’s in a bag, bucket, box, whatever…and save ‘‘em or sell ‘em.
I’ve got a good many small pistol primers and actually look for those to use up some of my small primers with.

I'll take all of that SPP 45acp y'all want to send me.

Keeps me from doing a primer swap on the 550

Agreed.
When I get a mess of 45acp, I just pay attention when I’m depriming…and chunk spp brass in a separate box. I do single depriming with the one-hand tool, then install primers with hand primer while im watching old cowboy movies. I rarely do priming while I'm loading.cartridges.
No spilled powder, no cussing, just treat spp as a different beast. I’m actually glad they make 45’s with spp. I have more spp than any other primers….and I get to use them on 45’s?!?…WOOO-HOOO!!!

I set them aside, reload when I have a couple of hundred, then use them where I can't recover brass.

Let them be someone else’s problem. Smart move.
