Ok, I've finally scrounged enough SPP 45 brass to make it worth doing a reloading run.

 

The question what is the effect on my loads by going from a Large pistol primer to a SPP.

 

Any suggestions? Or just start the load over again @ -10% and work my way up.

Those Federal and Blazer casings drive me nuts. I must have picked up brass after

someone unloaded a case of them because I'm getting one in about every 5 or so

with small pistol primer pockets.

 

What I do is load some small pistol primers and seat them and then load everything else

the same way. I collect all the ones with small primers and do them in a batch.

 

I made around 20 rounds or so a while back and from what I can tell they functioned and

fired just like the large primered casings. I don't think there is a need to change your

charge or anything else.

It definitely wouldn't hurt to start from scratch to be on the safe side. If you end up using the same powder charge I would run them through a chrono to see how they compare to the large primers

I have the same issue and have culled about 500 of these damn things over time. From what i've read around the net, it wont make a difference in the load (it especially wont increase your pressure). Even still, i'll just use mine for practice or a match where velocity/power factor doesn't matter and i can just leave the brass for someone like zoid to gather up.

I have been saving the Speer small primer brass I find. I would think your -10% load reduction is conservative. A smaller flash from the primer probably translates to needing more powder to achieve the same ballistics. Especially since 45ACP is a low pressure round to begin with, and 45ACP guns are beefy as hell, why don't you try your large primer load and go from there. You can do damage from running with too little powder too.

I wound up getting a couple hundred rounds of blazer brass as a break in for a new 1911, and found they had the small primers.

The flash hole size is my biggest concern. Was concerned the rounds might actually be too low pressure when using the smaller primer and smaller flash hole.

I just throw them in my scrap bucket.

Where do you find it? I have yet to see them, although I don't load much 45.

On the floor at Shore Shot. It is about 10% of the 45 brass I find. Speer lawmen uses it I think.

Want to work a deal on them Lou??

I dont have that many. Everytime I pick up brass at a range they somehow always get mixed in and I cant stand them. Let me check how many I have and I'll give them to you.

I rue the day some joker decided it was a good idea to invent SPP .45 ACP. Messes up my flow.

Same here. I've picked up Speer, Blazer and a ton of that "NT" (non-toxic) primed Win and Fed brass.

Totally.

lol.

 

How about this...

 

45 Gap is Small Pistol Primer... some early stuff was Large Pistol Primer. would of gotten some in the brass, blah.

 

Wasn't 45 ACP originally Small pistol primer?

Either make all of them large or small. It's really frustrating me. I can count how many

I get per 100 since when the primer doesn't seat I know it's a small primer. I remove

the primer from the press and then put them back into the primer feeder when I'm out.

 

I just counted around 22 out of 100 TODAY! That is a ridiculous ratio.

I also think I got my stash from SS. I have a bag of it I can show ya if you're curious.

I have about 4k of them. I load them the same as lg primer.

 

 

 

 

dan I have a bunch to give you next time we meet up. They are yours

Yeah federal champion is SPP.

I think they are making them both ways. Or maybe in process of switching production to full SPP. I was looking for some 45s on one of the ammo sites. They had 2 different types of AE 45s listed for different prices for the same quantity.

Looking deeper they specifically said that the cheaper (~4-5 bucks per 500) were SPP.

Federal champion should all be SPP now.

Federal AE should still be LPP.

I loaded up some of my Blazer SPP .45 last night with the same data as my LPP loads. I'll shoot them on Saturday and report back.

Please do, i have about 1k rounds of federal champion, same as blazer, and i'm wondering if the brass will be worth picking up and holding on to until i reload. I already have a stock of brass forming in .223 and 9mm.

WIN NT is okay. Federal NT is large but crimped so it's trash. I just figured out the latest one, the headstamp is (dot)Federal(dot). It's small primers. I just inspected a gallon jug and had to go through it again after trying to reload one. Now Blazer is starting with the SPP but the headstamp is the same. (sigh)

The .45 Frangible Ammo that Old Bridge uses for the Indoor Static Steel Matches are also SPP. I wound-up scrapping mine since no one wanted to reload frangible......

Just realized I never updated this thread. Must have posted in another one. I shot my SPP loads(same data as LPP) and they shot just fine with no noticeable change in perceived recoil. Need to get them over a chrono to be sure the velocity didn't change.

Thanks for the info. It's gonna be interesting to see if the chrono shows any difference

Someone ran this as a test on another forum awhile back. The results were a very minor velocity decrease (something like 10FPS, which is nothing) and a smaller standard deviation (more consistent)
