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.
