When I used to shoot USPSA/IDPA matches, we would go by "power factor". PF is bullet weight in grains times velocity in feet per second.
It usually gives a number in the 100 or 200 thousands.
You drop the three digits on the right and just keep or use the 3 digits on the left.
In your case, the PF is 250.
As a comparison, Winchester White Box .45ACP is a 196 power factor out of my 5" 1911s.
So you all's 10mm loads pack quite the wallup.
They should be good med'cin for bowling pins.
