I might make a suggestion to try about 80 to 90 grains of Black Mag'3 instead of the 777 as the velocity will be higher and the recoil softer if you have a rifle with a barrel over 24 inches. Even at 24 the velocity will be equal and the recoil softer. I killed an elk with a through chest shot using 90gr. BM3 and a 300gr. Hornady SST in my stainless Omega. I have one reply that says with short barrels the above does not apply although everyone else is seeing the same results I got. This is for the hunting post from Roskoe not the soft target one (sorry I forgot to specify).
