5.1 grains is a hit with my 44 mag. Dawn and i put 12 rounds down range with it. she shot an 1.5 in group and i put 6 out of 7 in a ragged hole just at 3/4" i will load up some more and take them to the range and run them over the chronograph. i am sure they will break 900 fps and that should be ok for her to shoot deer or hogs with. I have some of dicks bullets pcswchp that i will be trying next. i am sure they will run as good if not better.
on a side note the 5.1 shot tighter groups than the lighter 4.8 grains.
