The only way to find out is to chrono ammo out of your gun. What works in mine may/will not work in yours.
When I run factory, it's CCI Blazer Brass 124gr, Federal American Eagle 124 and 147 out of my gun.
Don't play the game at or close to 125pf it will bite you, I run 137pf never been bitten.
I was doing chrono at a major IDPA match and a gentleman, from Idaho, passed chrono on the last shot, his pf was 125001. I sought him out to let him know and said use a bigger shovel for the powder. A year later at a State match that I was working, he saw me and thanked me.
