1st - 52 gr TAC with a Hornady 200 gr RN hitting 2684 fps easily. This is the most accurate 1/2 inch or less groups from my rifle
I really like TAC for this and hot 35 Remington.
Just an unrelated side note I found interesting compared to this load above - Some factory 460 S&W revolver ammo I pulled down also used 52gr of ball powder and a 200gr Hornady bullet, but in this case 52gr of what I suspect is H110. Pulling those loads down was an eye opener for me! Shooting them was too!
