Small primer 44 magnum

[Mongo Safari]

My son and I picked up a handful of 44 mag cases at the range today. Four cases are marked S S and have small primers. Do you know who made S S cases?

Last year while policing my 45 ACP brass I picked up some Blaser, Speer, Federal along with my R-P brass. We found some of the FC, and all the Speer and Blaser had small primers. I tested a few rounds with my Bullseye load and CCI small pistol primers. They worked fine. I just need to keep the large and smalls cases separated. I'll save the small primed cases, cleaned and put away for a time when large primers go extinct for a while.

I've seen small primer .45 ACP (Blazer and a couple of others), but I have never seen small primer .44 Mag. I don't reload .44 Magnum, but I do reload .44 Spl. These days I discard the small primer .45 brass; I would probably do the same with .44 Spl if it had small primers.

Silly & Stupid ??

I have never seen any large bore revolver small primer cases.

The 454 Casull uses a small rifle primer. always has

Interesting...I wonder if these are SRP?

Great Thread. Thank you for sharing your
find on the 44Mag with a Small Pistol/Rifle
Primer, and also taking the time to post a picture.

I find it interesting. In all my years reloading
I have never seen 44Mag with SPP. I've
reloaded brass, aluminum, and steel cases.
I also reload 45ACP SPP. This is intriguing.

I would definitely use them, for the logical
reason Small Pistol Primers and Small Rifle
Primers can interchangeably be used.

I read before and believe it; Small Primers
support higher cartridge pressure and the
same as Revolver frame mounted firing pins,
along with durability.

The Best to you and your Endeavors.

This is the first I have seen of a small primer 44 Magnum case, but I am not surprised. Given modern primer compound, there is little reason for large primers in handgun brass today. Going to all small primers does make for better logistics when it comes to manufacturing ammo.

so what about the load data that calls for a magnum primer?

Look here: https://cartridgecollectors.org/headstamp-codes/ probably Israeli Military Industries.

I have some 44 mag IMI brass I just recently bought. I better check it for small primers.
The 454 Casull uses small rifle primers because of the higher pressures.

I didn't see small pistol primed 10mm brass mentioned by anyone. I have quite a few of those, along with 10,000 rounds of new, never fired, Top Brass 10mm LP cases. In my collection, I've got a .45 acp loaded round with a headstamp of 1957 that contains a small pistol primer, which I believe to be a Berdan primed case, so they've been around for awhile. I've yet to run across the SP primed .44 Magnum brass, but I'm not collecting brass like I used to.

In the SP primed .45 acp brass, I found an average of 50 fps less velocity with SP primers vs. LP primers with the same load, but the point of impact didn't change at 25 yards from the bench. That was from both 1911's and a very accurate Ruger Blackhawk 6.5" revolver. I know some people who have switched entirely over the SP .45 acp brass, as that was the only LP caliber they loaded and it simplified things by only needing one pistol primer for all their pistol calibers.

Hope this helps.

I would like to meet the genius who decided it would be a good idea to change the primer size on the 45 auto after 100 years. He obviously doesn't reload. Now every time that I get small primer 45 brass they go right into the trash.p, where they belong.

It's just not that hard to separate S from L primers.

Brass should be recycled, not trashed.

I swapped my 45ACP all over to SP a few years back and I have finally shot up all of my LP. Most of the brass I got from a friend. I had been shooting that old brass for 30 or so years and the opportunity to get further away from LP was there coinciding with replacing scared wore cases with something newer. I am through collecting brass for 44 so that is not an issue but having it show in 10mm? It is a good thing all of my 10mm brass is Starline.

Use small pistol magnum primers would be my guess.
