It sounds like you're getting excellent penetration and accuracy with that load. What more could a person ask for. Although some people might not believe the 80 grains of Goex 3f sounds all that impressive to their 120-150 grain loads, they could not be more mistaken. With a 385 grain Great Plains Conical being pushed, something down range is getting smacked.

Since I started loading and shooting my White Ultra Mag. I have learned that a simple 70 grain powder charge with these big conicals produced tremendous down range power. In fact I just got done nailing my bullet trap back together, since the constant pounding of the large conicals was basically driving the nails out of their place. These large spikes I used to nail the trap together, I kind of figured would hold the trap, but again, wrong. Not to mention even the ricochet of the conicals has cut one of the true ruff cut 2x6 in two. Looks like more repair is needed...

Nice shooting and as usual, a great report.
