Yah, I like Berry's for shooting .38 Spcl in my .357 Mag.
I used CCI 500 primers and Unique powder...started at 4.5 grains and increased to 5.0, 5.3, 5.5, 6.0 (don't ask why the 5.3; its a long story
). I used Winchester brass, Berry's 125gr. FP, 1.45" OAL, shot from my S&W 686.
anyway, I chronographed them, and wound up with the average FPS:
4.5 grains: 758
5.0 grains: 833
5.3 grains: 901
5.5 grains: 941
6.0 grains: 1,032
I really liked how the 4.5 and 5.0 felt...nice and smooth--of course, the gun is a heavy beast.
Good luck with your loads and have fun!
