45 ACP w/small primers? - Page 1

[ARCHIVED THREAD] - 45 ACP w/small primers?

Posted: 12/2/2019 5:05:19 PM EDT

I'm just getting back into the ACP after over 20 years and all the practice ammo/FMJ that I'm finding has small pistol primers. How long has this been going on? I'm sure the reloaders just luuuv sorting brass based on primer size.

Are there any pro's/con's to the small primers? I assume the small primers are cheaper...

but to they work just as good?

If this topic was beaten to death while I was happily shooting 9 and 40, I'm sorry to rehash it.

I think the word is they’re just fine except the huge pain in the ass nuisance factor.

I have no small primer . 45 ACP. F THAT. I AIN’T CHANGING.

This

Some claim it is better because of less powder disturbance when ignited.

They say 45 auto only has a large primer because its parent case did also...

First time I saw it was after the second obama ammo scare... I think manufactures just used it because it was all they had.

I say f it, I only keep large primer brass

S&B still uses large. While having small makes logistics easier I still prefer large in 45.

Meh, once you sort it just keep it separate until you have enough to justify loading a batch of small primer brass.

Lots of people refuse to switch and leave it on the ground I have heard.

This makes it easier to find brass for those who are willing to use small primered brass.

I have found a couple Large Primered 38 Special brass!

So primer sizes are not always chiseled in stone.

This is what I do. I reload a batch and then be sure to shoot it where it won't mix with LP brass. Then I just leave it on the ground. I Hate SP brass.

Federal HST and other high-quality duty loads in .45 Auto have small primers. If they were any less reliable I doubt they'd be pressed into a duty role. Anecdotally I've been shooting thousands of rounds of small primer .45 and they go off just the same as large.

I used to care but am now indifferent.

There are no lead free large pistol primers. So to have "Green" lead free ammo, manufacturers used small primers. According to reloading info, no performance difference.

Same for me. I only use large primers for 45 Colt, everything else gets a magnum small primer

for pistols. Makes it easier to stock a bunch of primers.

Also the small primer should be stronger as there is more material in the case head, but I doubt it makes much of a difference. Either way I use it for 45 super a lot.

That is an interesting point about case head strength. Although the 45 is a low pressure round it makes sense that the SPP cases have a smaller hole in case of a popped primer and theoretically may be stronger.

If I remember right, the powder charge for the 45 is not much different than 9mm and 40 so I doubt that it needed a large primer for even ignition, like say a 44 mag.

I don't reload, but I have shot a bunch of SP .45 acp (Blazer Brass). Shot great.

A buddy of mine that does reload said he can load the SP brass hotter. I don't know so I can't confirm.

***CHRONY DATA***

38 F, 30.06" Hg, 62%RH

.45 ACP 230-gr X-Treme CPRN @1.255" COAL
S&W 625 with 4" barrel

W-231 Powder 5.6 grains:
WLP - AVERAGE = 768 fps - ES = 15.1
CCI500SPP - AVERAGE = 714 fps - ES = 91.2

Red Dot Powder 4.8 grains:
WLP - AVERAGE = 777 fps - ES = 21.6
CCI500SPP - AVERAGE = 743 fps - ES = 85.0

Promo Powder 5.1 grains:
WLP - AVERAGE = 826 fps - ES = 73.9
CCI500SPP - AVERAGE = 796 fps - ES = 31.3

WSF Powder 6.2 grains:
WLP - AVERAGE = 720 fps - ES = 26.5
CCI500SPP - AVERAGE = 697 fps - ES = 48.6

So as you can see the average ES is tighter for the LPP loads than the SPP loads with all other factors held equal.
The average of the ES:
LPP = 34.28
SPP = 64.02

Furthermore, the average velocity is 35.25 fps faster with the LPP rather SPP.

So now we have hard data that says not only is SPP .45ACP brass annoying but it is also demonstrably worse.

Yeah, I don't have any complaints about SPP .45 from a shooting standpoint. In fact, the Blazer Brass was my favorite .45 ammo for a good while. It's weak- which made for pleasant shooting- but was still legal for USPSA major PF when I was shooting my G21. It was also a great bowling pin round as it had the power to take pins off the table for the set up we shot (not your normal pins on a sheet of plywood) but allowed for faster target transition. Oh, and it was cheap.

I've shot somewhere near 5 cases of just the Blazer SPP ammo and not had one issue. As a side note, I wonder what happened to this ammo? You used to be able to get it on SGammo for 24 cpr or so, but now you can't find it. When you do it 30 cpr.

A gimmick to identify lead free cartridges and the primers in them.
With over 10,000 LP TZ & TZZ cases I am just going to put them i a plastic back and set them aside.

No reason to pitch an otherwise reloadable case.
It might be needed some day.

Obviously, if you change something going in something should change going out. That is the heart of experimentation.

I certainly didn't expect the same results. Nor did I get them. And the change was all in the same direction. We call that a trend.

The data shows that with ALL OTHER THINGS HELD EQUAL you get less velocity with SPP than with LPP. That held true over multiple kinds of powder.

It has been going on a while. No big deal as I already have to sort crimped primers out of 9mm for swaging. Just culling out .45ACP small primers isn't a big deal. Even if one gets by and makes it into the primer station, I haven't had one damage the primer where it won't still easily seat in a normal case.

The other curve ball is that some cases, SIM rounds I think, have a thick, stepped inner wall to prevent the non-metal projectile from setting back while feeding.

So far I have only found one .45 case with this stepped wall.

Good point, I didn't notice the trend

. It looked more like noise to me, but they are ALL low. It is interesting that the Promo had a better extreme spread but the larger primers were better for the rest of the powders.

Basically you would have to up your powder charge slightly when you use the small pistol primers.

Did you happen to test small pistol magnum using the same loads? Wonder if that would get closer to large pistol primers.

I find your data valid. And I do feel bad since 100% of my 45 ammo is SPP. I only hope that the big manufacturers (Speer, Federal etc) take this into account and compensate somehow but I doubt it. Anything to save a buck. And I like the look of the LPP...when I carry, load, shoot 45, I want everything BIG.

Ideally, I would love for someone to test factory ammo, preferably from the same manufacturer, comparing LPP and SPP loads in the same gun. Maybe the ES, and SD variations in factory ammo is so "loose" that there is no statistically significant difference between them using LPP or SPP. (at least 10MM is still LPP, as far as I know...)

Do you want SPP(m) vs LPP or do you want SPP(m) vs LPP(m)?

And now that I think about it..WLP is for both magnum and normal loads.

Maybe I’ll try CCI SPP vs CCI SPP(m) vs CCI LPP vs CCI LPP(m) all at once?

Yay! I have a snowy weather reloading project to do!!

Yeah, supposedly WLP is for both normal and magnum loads, maybe that's why the large primers were slightly higher. If you already have large and small primers in normal and magnum then I think that would be a great test.

Thanks!

Did you happen to test small pistol magnum using the same loads? Wonder if that would get closer to large pistol primers.

Ya know...that’s a heckuva idea...

Loaded 6 rounds each of all 4 variations (SPP, SPP-m, LPP, LPP-m) using CCI brand primers only. 0.7cc red dot (4.9-grains) and 230-grain Rainier CPRN at about 1.270” COAL. Will update when I chrono them.
