Frank,

I think that's pretty much what I get with SR 4756.

With 7.0 gr I get an average around 810 fps at 15', using a 230 gr Golden Saber. If I switch to a 255 gr Oregon Trails LSWC, I get an average of 860 fps at 15'.

I also tried 11.0 gr with the 230 gr GS in AR brass for a 5" M625 and got 1105 fps average at 15'. I wouldn't recommend that one for anything other than a M625.
