Hey man, pretty good estimate!
I used 6.6 gr of CFE Pistol 158 gr XTP 1.585 OAL. CCI SPP.
I fired 18 shots and chronographed a few, though only 6 registered.
High 1002 fps, Low 944, Avg 971, ES 58.
My average is 130 fps lower than my goal of 1100 fps. Should I try some 6.7, 6.8, and 6.9?
Recoil and blast were mild / moderate.
They were plenty accurate! I only fired about 5 rounds SA, I fired about another 120 DA. (Total)
I had one light strike, though. Fired on 2nd hit. I fired 50 rds of CCI Lawman to be sure the gun would hit the primers hard enough.
I've noticed mild primer strikes on CCI priners but deep ones on Remington primers.
Perhaps for carry ammo I should use primers more sensitive than CCI's.
Maybe it was the primer, maybe it was me, I dunno.
