I load APP according to mfg's data in my better third's .38 CAS ammo. It smokes big and recoils little. Although I haven't chronoed her loads, it doesn't appear to offer much velocity.

I load FF 777 according to mfg recommendations in my CAS 45 Colts, 38 Spec., 44 Mag and Spec and a few others. I also load 777 for my 1895 Marlin Cowboy with a 405 flatbase. Good accuracy. Good velocity. Good smoke. No sweat concerning lube type. If I could keep only one powder for the rest of my days, it would be Hodgdon FF 777.

I load FFg Goex with the same 405 gr. flatbase bullet for my Trapdoor. FFg is also used for my CAS shotgun.

YMMV, Rich
