As a complete aside, I couldn't get 286 TSXs to go over 2000 FPS in my rifle. I stuffed so much powder in the case that the bullet stuck in the stem of my seating die (I ended up using the RN stem out of my 416 Rigby dies set). Still couldn't get over 2000. I switched to a 286 Norma RN (old stuff - wish I could find more) and RL15 (I believe 61 or 62 gr which is over what Ken Waters wrote in Handloader from January 1992) and managed to get them to 2350. My theory is that the 286 TSX is too long for thee 9.3x62 case and possibly too tough, though I didn't ever get to use it on game. Time to try those Normas out on a moose though.
