After all a 165 TSX at 2900plus is a far better killer then a 300 win mag with a 180 grain factory load shooting a cup and core bullet.
Can't agree with that.
Killing Power figure at 100 yards:
.30-06 Springfield (150 grain at 2920 fps) - 37.3
.30-06 Springfield (180 grain at 2700 fps) - 49.2
.300 Winchester Magnum (180 grain at 2960 fps) - 59.5
