As you have a 6.5x06 and like to mist a ground hog, let me show you something, a real mist maker, that you can do:
This is from my 6.5x06 with a 85gr Sierra and 48.5 gr of H-322 for a nice 3,755 fps, it is a max load. The rifle is a 700 BDL blue printed action with a Douglas Air Gage 26" barrel. It makes two reports, one from the muzzle blast and the other from the impact, like boom-boom...... H-322 is the replacement for Hi Vel #2 listed in the Ackley books. Only meat left in the skin is the skull and in the tips of the paws, on a 35 pound whistle pig, sometimes there is no skull, just meat in paws. The rest is a funnel shaped fine red spray on the grass behind....
Oh, the impact will disintegrate a gallon jug of water, even the handle is shattered. Try it.... you will like it a lot.
