I like a 124gr with fast powder. Not as soft in the hand as a 147, but I am back on target quicker. My CO gun is a CZ P10C with a Holosun HS507C, and my load is 3.8gr of Titegroup under an RMR 124gr FP FMJ "Match Winner" at 1.100"
Shooting the classifier "Roscoe Rattle (13-04)" firing 6 rounds per target, the dot did not leave the window.
