USPSA Minor Load for Czechmate

[chapo]

Found nothing specific on this gun plus AA7 for minor. But I am currently shooting 10.3gr of AA7, over 115gr CMJ, loaded to 1.165" with a 10lb spring, yielding 169 PF. I'm now looking for some feedback on a minor load (125-164PF) with a czechmate and same bullet and powder. Also looking for advice of recoil spring weight. Thoughts??

Not n up on PF, what fps does a 115 require to hit this?

Can you confirm this is a 9mm Luger?

For an uncompensated pistol you'll want to use the heaviest bullet with fastest powder to reduce recoil an minor power factor.

Power Factor is bullet weight times velocity divided by 1000.

125 * 1000 / 115 = 1087 fps

Aren't most people who are shooting 9mm minor, using 147 gr bullets?

I much prefer 124/130 for minor. The recoil seems a little flatter and snappier. The heavies in a semi make the gun feel sluggish. But for revolvers I much prefer 160-170gn bullets.

Yes. Shooting 9mm major.
