In today’s world you can’t always find the primer that is specified for the handgun load you would like to produce.

I am almost out of small pistol primers but have plenty of small pistol magnum and small rifle primers in stock.

Assuming that my firing pins could handle the hardness of a primer change is there any reason why I could not go to the bottom of the load for that cartridge and slowly work up with the hotter primer?

I have a good chronograph I could make sure that I’m not exceeding the muzzle velocity of the small primer load.

What say you?

Thanks for your input.

Been discussed here before. I would'nt drop all the way to the minimum load; drop .5 gr. and see where you're at on the chrono.

Subbing a small rifle primer in place of a small pistol primer produced no noteworthy changes in 9mm ammo for me. Others had similar results. Check out this thread:

Thanks Waders….
Looks like I shouldn’t have any problems subbing the small rifle primers in for the small pistol primers. That’s very encouraging!!!

Cheers.

If you do any formal/semi-formal testing, please post your results in that thread I linked. More data is always better.

Good luck!
