Anyone loading SPP in 45?

[XDRoX]

I got lucky and someone on another forum gave me a few hundred small pistol primer 45 cases. I have been wanting to try SPP 45 for some time now. It will be much more convenient not to have to change the primer mech's on my 550. From now on everything will be SPP. I only load 9mm, 45, 38spl, and 357mag.

So I loaded some up today and will be test firing them tomorrow morning.

As you can imagine data is hard to come by so if anyone has any please share.

Here are the 40 rounds I loaded today.

4.4gr of WST under 230gr RN @ 1.240"

Chris, JMB is rolling over in his grave cursing the person who has defiled his beloved .45ACP by using small pistol primers. Any of those cases that I happen to find got straight into the junk brass box in the shop. Bad, evil and unnatural.

Lol, then he'll really be turning tomorrow when he sees me shooting them in a vintage 1930 1911 It's one of the most valuable guns on my collection, but it needs to see a little range time now and then, right?

But seriously, I have been reading articles stating that the new SPP 45's are actually more accurate than the large ones. And changing primer setup's is a hassle that now I won't have to deal with.

I can't wait to test them.

That is just wrong shooting SPPs in a 1930 M-1911 framed .45ACP pistol.

Think I will stay what works for me (old guy) since don't think my reloads can get more accurate than they are. The 650 hates SPPs mixed in with the normal LPPs......
I can't wait to test them.

Let us know if you see a difference in accuracy.

ive only run into about 20 of those cases

and each one made me so angry i threw it so far it will never be seen again

but if its all you got its not a big deal although to me small pistol is often harder to get than large pistol

i like it when the case says nt or some identifiable mark but i ran into some cci that used small and were not stamped any different

One of those SP cases made it way into my progressive press
A glob of LPP metal and anvil was crushed into the small primer pocket
It was a CCI primer and looked like a piece of popcorn stuck in the primer pocket
I am surprised it did not ignite

.45 SP brass is dangerous. It goes straight to the trash. Especially when I have 10K of large pistol brass

I abhor changing primer sizes on the Dillon. For me it is the other way around. I usually load LP ammo
I prime my SP brass off press and pull the de-capper for the .357 ammo

Culling your SP brass from you LP brass is going to be a lot more complicated then you think as one or two is sure to make it to the press

Were you able to find any load data for the SPP cased .45s? I just found about 2 dozen mixed in with my brass from the range.

[XDRoX]

No, but the rounds that I loaded in my OP worked great. The SPP hardly make a difference. Slightly less pressure/velocity.

[Stryfe76]

Sounds like a good plinking load. I'll have to try a few with some Bullseye. I wonder what magnum primers would do with those cases.

[Chief-7700]

Load this evil SPP brass just like you load the LPP brass. The SPP brass is just not worth the effort to change out the priming system on the XL-650.
