I shoot both the 250 gr Nosler AB and the 286 gr PT (and Norma Oryx) in my 9.3x74R. Velocities are 2550 fps and 2350 respectively with handloads. Accuracy is in the MOA range in my 22 inch Number One Ruger.
I would imagine performance of these bullets would be similar? I certainly do not worry about their ability to kill any game that I would shoot?
For my needs, the 250 AccuBond is a great bullet for the 9.3 (.366)caliber rifles. With the AccuBond's high BC and velocity of 2550 in my 9.3x74R, it meets any need that I have for elk, bear or any use that I can find?
I have not tried the TBBC, North Fork or other premium bullets for the 9.3mm but I do have some Norma 232 gr, 286 Oryx and Speer 270 grain bullets to try?
