Reloading 9mm with Small Magnum Pistol Primers?

Boolit Master Join DateFeb 2012LocationOregonPosts198

I was all excited to see CCI small pistol primers on the shelf that I did not notice they were Magnum until I got home. I now have 2k primers I hope you guys help me figure out how to adjust my powder so I can use them.

I am using 356-124tl with 4g of Unique and Recluse lube. I am shooting them out of a 1911 9mm. 4g of Unique is the lowest recommendation and I think 5g is the peak recommendation.

Can I adjust my powder so I can use these magnum primers?

Thanks

I use mag primers almost all the time regardless of whether or not they are called for. All you have to do is back your load back 10% if you are at mid range or higher and watch for pressure signs. You're not even close so I'd just use them. FWIW, I've never gotten any pressure problems doing this and I've been loading over 40 years

I believe mag vs std primers is only a significant factor when you get near max loads. Since your already at the start load, I wouldn't worry about it. As always, work up from there. Those with more experience than I will chime in shortly...1...2...3...

I've only done it with .38's. I was in the middle of the load range so there was no issue.
I would do what NSB suggests in the above post.

I loaded I think 30 9mm about a month or so ago with CCI Small Pistol Magnum primers I've had since 1993. The loads were mid-range Power Pistol and their performance was no different than with the non magnum primers.

I had intended to load a lot more, but an interruption stopped me at 100 rounds a week ago using that same lot of primers. I'll very likely shoot the 100 before I load any more, but my intention is to use them in 9mm and enjoy them.

Sounds like I am ok with the load I am using with the magnum primers. Well looks like I can keep shooting a little longer

I load whatever I can find. Mags seem to be more redialy avaialbe these days.

I use them in 9mm, 38SP, 40 S&W, and the large ones in 45LC.

As stated above....just back off your standard load ~10% for starters. My standard loads are 65-70% normally.

My results have been the same as bangerjim's. Go for it.

Agree with all of the comments. I've used Mag Primers for all loads with no difference although I do not load to Max with them
