Okay, BD, I have used the 9.3X62 for almost 30 years, and most of the game it has killed was using the 286 gr Norma Dual-Core ahead of a very stiff charge of IMR4895. I prefer not to post the exact charge weight because my rifle has a very long throat and yours may not.
Suffice it to say that I can get easily 2500 fps with that bullet, but load it down to 2400 because that is plenty enough killing power.
The rifle is an old pre-war Model 70, and it shoots into less than an inch and a half with the Normas, the 270 gr Speer, and the mild-steel jacketed 285 Kynoch RN bullet made for the 360 No 2 cartridge.
That Kynoch bullet, BTW, took down the largest antlered moose I ever got, a 64" monster. The guy I was hunting with had spooked it bad, and it was running flat out across in front of me at about 60 yds. One shot into the lungs and it was all over in about six seconds. All but the work, that is.
