Thanks for the range report!

I was wondering if you had a guess of the temperature while you were testing, because I seemed to get an approximate 50 fps higher velocity with a 20 degree temperature rise. From my sketchy country boy testing, it appears that even though my rounds are 0.020 inches shorter and have 0.2 grains less Power Pistol, they are getting down range just a tad quicker.

I suspect we’d be seeing some closer numbers if I owned a real pistol like a BHP, instead of a poly Springfield.

I guess when the Kahr manual says to load using the slide release, well there is a reason. I find the 115 gr Berrys with 6.2 Power Pistol to be a rip snortin' load in my little poly Kahr P9, but the little pistol can really punch the holes close to each other.

Thanks again!
