Power Pistol at 6.4?

Off subject, but I was wondering if you had clocked that load? For jacketed bullets, my Lyman manual shows the 6.2 as a mid-range load and the Lee shows it as a starting load.

I'm using 6.2 grains of Power Pistol under a 115 gr. Berry RN, set at 1.120” with CCI primer in R-P brass. The load “felt” hot, but produced the best groups out of the ladder I tested a year ago. I don’t own a chronograph (yet), but a friend has shown up at the range with his a couple of times. Last fall, temp in upper 60’s, I tested 5 rounds and got average of 1192 fps with 37 fps extreme spread. A few weeks ago, I tested 5 more rounds and got average of 1252 fps with 60 fps extreme spread at temp of upper 80s. Pistol is Springfield XDm 9mm stock.

Since I’m slightly over Berry’s recommended upper limit of 1200 fps, I was wondering if you had chronographed your loads?
