In a Kimber I tried 168 gr TSX, 180 gr Accubond, 180 gr TSX and the 200 gr Accubond. The 200 gr Accubond had the best accuracy and the loads I tried were with IMR4831 (63.5, 64 & 64.5 gr, 2834 fps to 2887 fps) and RL22 (66, 66.5 & 67 gr, 2851 fps to 2888 fps). Since the rifle was not mine, I decided to not push the envelope and load the most accurate load of 200 gr Accubond and 66 gr RL22, .020" off the lands, and Fed215 primer.
The load was not compressed much and I use a Lee Factory Crimp anyway. I thought a velocity of 2850 was pretty decent for the 300 WSM
. Closer to 300 win mag velocity than it is to the 30-06 velocity.
