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.

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. 'holic

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 trying to push the performance envelop with less than optimal components. But optimal and suitable are two very different word in reloading.

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!

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. Jake My pistol and rifle are only tools.
