Ended up trying a load of 65 gr of H1000. I found a similar load on 6mmbr.com. I forgot and left the target at the range, but at 100 yards, I was getting 1/2 to 3/4 MOA , with a velocity about 2850 fps. I took 5 shots at 1767 yards and hit the big target (48" x 48") 4 out of the 5 shots. I didn't try for the smaller target because I ran out of ammo. I think with a bit more tuning, I will have a great load.
I didn't see any evidence of the bullets blowing up.
