Practicing for my elk hunt in October. I always zeroed my rifles and muzzleloaders at 100 yards. However, the farthest shot on this hunt will be 300 yards as my 8x57 bullet drops alot between 300 and 400 yards I will not take a longer shot as I am afraid I may wound the animal. I am shooting a 8x57 .323 175 grain Sierra Prohunter at 2650 fps which has a sectional density of .240 and a ballistic coefficient of .381. An article on the internet said for long distance hunting, hitting about 2" high at 100 yards is a better zero. Not asking anybody to do any calculations. I think my balistics are similar to a 308 so hoping some of you know your preference off the top of your head. Thanks in advance for all replies.
