With the 3 bullets that we tested with my dad's Remington 721 (24 inch barrel) here were our best loads. MV is average of 15 shots 15 feet from muzzle, accuracy is average of 5 3 shot groups.
1. 150g NP, 58g H4831, 2937 fps, 0.787 inches
2. 150g Woodleigh, 63g Magnum, 2886 fps, 0.656 inches
3. 150g TSX, 56g 7828, 3081 fps, 0.344 inches
Dad ultimately went with the Woodleigh, due to the size of the whole and penetration. Used it a while, but went back to the 150g NP last year with good performance on the Kentucky whitetail that he used it on.
