On my last range trip with my M&P40, I had both major and minor power factor ammo. While the ammo loaded to major pf had more pep to it, I noticed that my groupings were better than shooting with the minor pf ammo. Anyone else experience this?

No, not unless the minor power factor load is just plain inaccurate. Which is a possibility.

Maybe that's the case. But both types of ammo were purchased from Atlanta Arms & Ammo.

I highly doubt that'd be the case with me. From my reloads to factory ammo

my groups noticeably open up.

 

I do shoot my Kimber in 45ACP very accurately, but that's also a full size,

all steel gun so...

 

But if you're comparable with both in USPSA you will do better because w/ major

you lose less points for hits outside the 'A' zone.
