BB, I didn't see your post before I went off,I tried the barnes with h110 and couldn't get very good accuracy at 100 yds ,it was pretty good at 50 though,I still have some so my next project is to try them with power pistol.The reason why I went with theC.E.B.is they gave me the better accuracy of the two with h110.
I have data from Cutting Edge Bullets for their 240 grain raptors showing a max load for power pistol being 18.9 grains @ 58000 psi with a M.V. of 1761 fps from a 7.5 inch barrel also from load data .com showing max load of 18.0 with aM.V. of 1569 fps, no pressure data but a caution that this is for a freedom arms model 83. I went up to 18.5 and had no pressure signs but lost the accuracy I was after.So I'll stick with 18.0
BB-I just tested the 250 grain barnes xpb with power pistol and it did not shoot well,2 5 shot groups @100 yds both+4 inch groups(about the same as I was getting with H110) and velocity was very erratic 1573-1654 fps and noticeably more recoil.I used 17.5 grains instead or 18 because of the length of the barnes over the C.E.B.
