9mm power factor question

[KDX]

I reload 9mm with 124gr plated Berrys bullets and 4.2gr Titegroup (for my CZ) and was wondering approx what power factor these would have. I'm thinking of buying a Gen 4 G17 and supposedly they run well at about 133 power factor. Don't know much about this stuff. Thanks in advance.

Wasn't power factor some mix of velocity and bullet weight? IIRC something like a 125 grain going 1000 fps would be power factor of 125 and I forget the rest. If I'm wrong it wouldn't be the first time. Bullet weight x velocity and adjust the velocity up or down so it hits 125,000

I loaded up 2000 of the Berrys 124g HP with 3.8g of Titegroup.
Over my Chrony average FPS was 1010 for 125.24 Power Factory
I loaded them short to try in my Shadow 1.06 COAL

you might find anything less than 135 may be a little too close @ crono time in a real match. temp., alt., hum., tester & their equip , it's a ##### to drive 100+miles & not make PF
