The data that I have found says that, when substituting mag primers for standard, drop your powder charge by one full grain and start over on load development. That has worked for me on my 9mm load. It was originally 4 grains of Red Dot with a 124 grain lead rn. Now, three grains with a magnum primer works just fine.

I just hate to have 800 primers on hand that are useless....
I'll get to some books and check the internet for any possible load data that can be verified and validated.
Thanks for the thoughtful/insightful replies everyone!

I cannot see why they would not be suitable for use in the 9mm parabellum. Having said that, you would probably want to start from scrach with a load for these. Basically, the starting load for the slowest published powder for this cartridge.

I haven't loaded the 9mm for years. Is there any published loads for it using 2400. If so thats where I would start.

For me, just getting an accurate load that will cycle the pistol 100% would be outstanding success. No use...

It would be a good idea to contact the manufacturer. It may be that they have a stronger cup to resist magnum pressure and might not do well with a light firing pin strike. Better to ask someone who has the facts.

I'm not telling you anything you don't know already but, if they went to the bother of naming them "Magnum" then, there probably is a good reason NOT to use them in light loads. It may not matter at all, depending on which maker, but I suggest you shelve them until you have found two reliable sources in print that give 9x19 loads with that type primer.

If a person fell into a few (several) hundred of these type primers (Magnum Small Pistol) can they beused to safely load 9x19 or other pistol cases, or are they a specialty primer?
