Small primer for 45 acp brass?

Must be that mine shrank in the cleaning and drying process.

Maybe. But I've got a couple hundred Blazer SPP and only those 7 Blazer LPP. I'm guessing they came from before Blazer transitioned to SPP. I only mention it because Blazer LPP is still out there

 

[Rugerspyderon]

Federal does that as well

swap them .... they could come in handy push comes to shove you run out of large primers .... I understand that you have to keep them separate and an extra step in the sorting sorry I didn't come up with the idea

RWS also has some small primer 45 brass.

When the .357 Magnum first came out, it was all large pistol primer brass. In 20 or 30 years people will probably be cussing LPP .45 ACP brass.

There is no functional requirement I'm aware of that requires the .45 ACP to actually need a large primer.

I have over 2500 SP 45acp casings. I bought 2000 Winchester NT once shot for $.05 apiece (from a cop who collected at the practice range) didn't know I'd have swage them all

Every time I go to my indoor range they collect everyone's brass and give it to me. So I sort through the casings for my own and other SP brass and inspect, all Blazer I've encountered is SP. Dillon 550 here also and don't have to switch between 9mm and 45's, it's very convenient.

Small primer .45 works, is nice if you also load 9mm (no need to change priming parts)... but you also get an IPSC PF drop of about 20. Slower ignition of powder.
Ammo that is otherwise identical and measures PF 170 with large primer is PF 151 with small primer, in the same gun.

Help here please, what is PF drop? I have seen some folks writing that there is no difference revealed in testing between LP and SP, but common sense urges me to believe there may be some difference - if not why would they have magnum primers?

Federal was the first that I know of to switch to small primers. Oddly, I bought a 100 rounds box at Wal-Mart last month, and I shot them yesterday, They're large primers.

Power Factor is a means of evaluating one's ammunition in certain action pistol sports to determine whether one is shooting major or minor power factor. Most serious competitors shoot major power factor, I think. IIRC, it is bullet weight times velocity (or something of this order) renders a number which will then determine which classification one will shoot in. HTH

I'm getting geared up again for 45 ACP, and looking to buy brass. I ran a search and found this thread, glad I did.

As I understand it, 45 ACP is a relatively low pressure cartridge, and I have not heard of primer pockets loosening with use. Nonetheless, with small primer pockets in 308 class centerfire rifles, the reports are generally consistent that such brass will last longer before the primer pockets loosen, and brass evidencing this issue must be scrapped.

I wonder whether the small pistol primer type 45 brass mightn't last a little longer? RWS makes good quality ammunition, I suspect their brass is also pretty good. Perhaps I'll buy some to try.

Me likey the RWS brass.

Like already said, good to have when LPP dry up. I was shooting 357 and had plenty of SPP when Sandy Hook came along. Then I started 45 acp and no LPP were available! Now as i come across 45 with SPP, I just set them aside in their own coffee can for later use. I usually find the SPP when my Lee auto hand prime will not set the LPP! Don't know why it just won't!Good reloading, Catpop

I've got maybe 200 blazer and federal spp 45acp cases. They annoyed me at first. I kept shooting and reloading them over and over thinking they would die and I'd never have to deal with them again. They've all been reloaded at least 10 times and I've come to like them. Some have been fired so many times that you can hardly read the headstamp through the extractor marks. It might be my favorite brass because they feel more accurate.

To the OP: I say sort them out, use them in separate shooting sessions from lpp brass, reload, and repeat. Then again, I reload on a single stage press so if one gets mixed in with lpp it's not as much of a train wreck as it would be on a highly automated progressive ("highly automated" is probably not even the right phrase).

45 is realitively low pressure, I have cases that have been reloaded so many times the headstamp is gone.
