As to bullets, my M46 in 9.3x57, with 3-9X M3200 scope & bagged, shot under 1" at 100 meters with all bullet weights. I shot Norma's Vulcan in 232gr., sized down 225gr. and 235gr. .375" Speers, 270gr. Speer(too soft(imho), 285gr. Privi RN, 293gr. TUG and sized down 300gr. RN .375" Hornady. The .375's were sized down, drawn, to .367" which was the largest size my rifle would allow in the chamber. The rifle was over sized at a .370" groove diameter.

I drove the 225gr. at 2,550fps, the 232's at 2,450fps (same load), 270's at 2,300fps, 285gr. & 293gr. at 2,200fps and the 300gr. RN's at 2,175fps. THOSE would also be a good, all round load for this rifle.

2,175fps was the original 9.3x62 factory load for both softs and solids in 286gr. weight, as noted by John Taylor in "African Rifle's and Cartridges for the 286gr. bullets.

This, BTW, is the load that gained the 9.3x62's reputation in Africa. John Taylor wrote that the increase in speed for the 9.3x62 in 1923 or so, was unnecessary as it worked perfectly at 2,175fps.

I didn't get around to testing the 286gr. Hornady SP, but that is the bullet I'd probably have settled on for everything. I'm sure my rifle's propensity for shooting under an inch with everything, would still hold with the Hornadys.
