Karl-I've tried h110 with 250 grain barnes in .5 grain increments from 27.0-29-0 and gotten 1530-1720 fps respectively, according to my notes all have given me under 1.5" accuracy at 50 yds but 4"-6" accuracy at 100.Oh how nice it would be just to stuff your favorite bullet in case full of H110 and go huntin'!!
