If you have a Remington 770 30-06 zeroed at 50 yards what is the bullet drop or rise at 100 300 and 750 yards the rounds are 150 grain Remington express pointed soft point core lokt?

For the 168 grain Core-Lokt, if you zero at 50 yards, you will hit 0.3" high at 100 yards, 13.4" low at 300 yards, and 157.9" low at 700 yards. 50 yards is a very close zero for a rifle. You might want to think about zeroing at something between 100 to 300 yards. If you zero at 200 yards, you will be 0.8" high at 50, 1.9" high at 100, 8.5" low at 300, and 146.4" low at 700. YMMV.
