As far a jacketed ammo, I load 124gr JHP Precision Delta using 5.2gr, OAL 1.100". They are hitting around 1040fps on the chronograph. This is my standard 'range' load. Bayou Bullets, 124gr LRN, work well with this load also. Those I can load to 1.130, (one of my pistols has a short throat). I've loaded the JHPs up to 6.1gr, they're getting a bit 'warm'.
