I have a Redhawk .44 Mag w/7 1/2" bbl. I carry when I hunt hawgs. I presently use 8.6 grains of TiteGroup and fling a .429 Speer 300 gr. SP. What do you think the velocity might be? I have chosen this load because the recoil is only about a 4" jump and I can group it very well in rapid fire. I know the bullet is heavy enough and was just looking for a semi-educated guess on velocity.
