Mixed Magnum & Non-Magnum Pistol Primers

[MMH]

I have about 60 primers that were left in a primer tube & I am not sure if they are magnum or non-magnum. I do know that they are large pistol primers. If I were to use these for mild 44 magnum plinking loads (8 or 9 grains of Unique pushing a 240 gr. LSWC) would it make a big difference? Any safety concerns?

I sold my .357 mag revolver, but still had some magnum primers. I used them for light loads for my 9MM without any problem. I'm not saying you should, but that was my experience.

long at it's a mild to middle of the road load of unique you'll be fine .

I use Winchester large pistol primers in that load range. They're labeled for standard or magnum loads. One of the reasons I use them is so I only need to stock one primer for both uses. They work fine. However S&B has lately been used due to their price. Learned awhile back to label equipment with a piece of masking tape and magic marker. So if I do walk away from them, or dig something out to use I'll know what the last settings were and what I was using it for. Doesn't take much to distract me.

I use CCI magnums with 8 gr of Unique and a 240 with no problem. I didn't want to stock 2 styles and needed the magnums for the load with 296 so I just used them in the Unique load from the get go.

That said, if you are really concerned and know who made them, call the maker. I know Winchester color codes the priming compound for various primers. The manufacturer may be able to set you straight.

If it is not close to a max load with Unique you should be fine. If you load with 296 or H110 you could use them for that. After a well seasoned .44 mag guy on another forum said his groups shrink drastically using a LPP vs a magnum LPP I have been using non magnums with 296. My groups did shrink quite a bit vs the magnums.(not for cold weather though)

Use them up. You will be fine as long as you are staying under anything that might get close to excessive pressure and the 8-9 grain of Unique would be well under that.

Usually the priming compound are different colors. That's what federal does anyway.

Agreed.....plink away.

What if you loaded them using a 44 Special load and shot them out of a 44 Magnum... like a 44 special +P?
