SP vs. LP Primers .45ACP for 185gn SWC Bullseye
Other than making sure to use the right size per empty case, is there any drawback as far as accuracy and reliability between the sp vs. lp for .45ACP.

Reliability - no issues, accuracy - never checked.
I am holding my SP .45 brass in reserve, just in case there is ever a time when LP primers can't be found. A buddy shot SP .45 because he stopped shooting .38 special and ended up with a surplus of small primers. Never heard he had and issues with accuracy.

I routinely pitch the small primer 45's. They screw up my reloading process, and I don't see enough of them to make saving them worthwhile.

If I meet the individual responsible for deciding that SP were a good idea I might end up in jail
Those darn things will lockup a Star reloader really bad.
Definately takes the fun out if reloading when I run across one.

Color me the oddball but I like SPP in .45's. Its saves me time from changing over the primer bar in my 550B when running .380, 9mm, .40 and .223 calibers.

It also means you don't have to mark your brass because nobody is going to want to take it instead (generally)

I believe some nutcase found evidence that the SPP's were minutely more ignition consistent. But, I suspect it really was a corporate manufacturing cost saving move.

It was originally for non-lead primers. With 9mm and 40 being huge indoor range usage, it was easier to make SPP 45 brass to make life simpler.

True, and another upside is that I get a lot of free brass from the LPP crowd at my club.

Any idea that moronic had to come from a committee.

When it came time to get an indexing press I was looking at either the 650 or 1050 Dillon and SPP in .45 brass is one of several reasons I went with the 1050. It's inline swagger catches them. I manage to catch 1 or 2 a month. It helps that I no longer pick up any brass and accidentally pick up a SPP case, if it doesn't go in my net you can have it.

All being said , unless you are shooting a revolver do not show up to a match with SP brass. 30/40 pissing off angry people with guns is something I have worked my how life to avoid.

Reminds me off when I tossed Remington STS shotgun hulls reloaded with RIO primers on the ground at Trapshoots. The scavengers would bitch when their STS/winchester primers would fall out off the shells when reloaded. Geez, they were free! Lol

Re: SP vs. LP Primers .45ACP for 185gn SWC Bullseye
So many times I've turned around to pick up my brass and it's all gone, REALLY!!! That's when I announce that I shoot small primer 45's. My brass makes it back to me and I don't have a problem after that. I still mark my brass though.weber1b wrote:It also means you don't have to mark your brass because nobody is going to want to take it instead (generally)
There is a powder charge difference between SP and LP. With Titegroup and 185's it's about 3/10ths of a grain. Probably less with heavier bullets.
Accuracy is all there.

I shot an IDPA match with my BIL. I was not amused by the groups tendency to pick up anyone's brass and claim it as theirs, my marks on the brass notwithstanding. There was one guy in the group who was always ready to pounce when the round was over and it was brass pick up time. I always figured if I was to go back again I would load up some SP rounds and just let them have at them.

Which direction? Do you use 3/10ths of a grain more, or 3/10ths of a grain less, with small primers?
Re: SP vs. LP Primers .45ACP for 185gn SWC Bullseye
Use slightly more powder for small primers because there is less brissance as compared to large primers.bdas wrote:Which direction? Do you use 3/10ths of a grain more, or 3/10ths of a grain less, with small primers?
My 185 JHP large primer load uses 4.0 Titegroup.
My 185 JHP small primer load uses 4.3 Titegroup.

I think they should have to buy back all small primer brass. Never in gun industry have they done such a dumb, unsafe product. 45 gap, 38/357 others, 40, 10 mm
All different for a reason.
My opinion.

I have found one and only one use for SP 45 brass. 400 Corbon uses SPM or SR primers. I run them through the Corbon dies and if they live/resize I take them to the field and blast away. I never feel bad about loosing them.

I do that at my local public range. Takes about two weeks and then they stop picking up my brass.

Re: SP vs. LP Primers .45ACP for 185gn SWC Bullseye
Its been a while, but I shot IDPA and IPSC for a lot of years. The way it was done then was when each shooter finished, a couple guys would paste targets, and the rest picked up his brass, and gave it to him while the SO was scoreing. Not really the rest, because the shooter on deck, and in the hole are exempt to get focused for the match. There is also a guy recording the scores as the SO scores.
That said, I always bought the cheapest once fired brass, and expected to lose a lot. When running and gunning, brass get throwed all over, and shooting in sand/grass/ or whatever, it gets lost, stepped on, etc.
For large matches like State etc, it was in the program that it was a "loss brass" match. The brass went to the RO/SOs as a tip for doing the work.
Again, maybe things have changed, but there isn't a reason to be spraying your new brass.
