Can I use…

So when y'all are saying to backoff a little on the powder load, is that off of the minimum amount they show in the book?

Check you primer holes! Some of the companies are using small pistol primers for 45 now!

yeah I ran into that stuff the first time I started reloading… i broke out on 45acp as a teenager.

I usually back off the max load stated in the book when going to a mag primer.
If you are at the minimum load and change primers you will be fine at least in my testing in 38-357 and 45.
Then work your way up and watch for signs.

I have changed primers with ball powder in .223 cases and seen as much as 100 fps difference between primers.
When I tested the same primers with stick powder and in .223 there was not any more than 25fps difference.

With that in mind different powders will absolutely act different when you begin trying different primers.

Small primer 45 has been around for quite some time.

Been happening for a long time, it’s usually Federal and Blazer

back off of your pet load. So, for me if I’m doing

4.0 grains of TiteGroup with a standard primer,

I’d want to back off 10% - - 4.0 minus 0.4 = 3.6 gn with a magnum primer.

So in my case I’d probably load up


5 rounds @ 3.5

5 rounds @ 3.6

5 rounds @ 3.7

5 rounds @ 3.8

and see where that got me. Likely 3.5 wouldn’t cycle/eject reliably and 3.8 would feel too hot. I’d probably end up right at the middle two.

hope that helps.

I use shotgun powder exclusively for 9mm. I’ve been barked at a few times on the internet for it. I tell them it’s okay to cross over shotgun to pistol generally, but not the other way around. But - ya Gotta be smart and safe at any rate.

The powder I started with was the only powder I could find after the Obama inauguration - Alliant Blue Dot. Haven’t used it since and moved onto Red Dot and Clay Dot. Accurate and low recoiling. That’s all I need!

I used blue dot in .40 cal for a long time with sissy loads to punch paper and ding steel. Had a very unique smell after firing.

Every time I run on to one of those aberrations It goes into the scrap brass container. Eventually I hope to eliminate those from the shooting world.

Mag primers: Most of my loads are more middle of the road except for a couple of specialty rounds. I have used Mag primers in place of standard. I backed off the load a bit and made sure I stayed above minimum load. My understanding, right/wrong/indifferent, is for safety never go below the minimum load. Too little powder in too much space can give you problems better left unexperienced.
