Hey Everyone,
With the current primer situation I find myself with only magnum small pistol primers to load with.
Some poking around on the Internet I found multiple instances of people recommending a 10% reduction in powder charge when submitting magnum primers.
I had been running 5.0gr of SW Auto Pistol behind a 147gr coated bullet.
I dropped the charge to 4.5gr and tried it out. I am seeing primer deformation that is quite different than what I have seen in the past. If it went all of the way around I would call it "crateting". But it is just on the sides.
I have never seen anything quite like this.
What do you all think?
Thanks
S.
