[QUOTE="Kelpy, post: 1126275, member: 8876"] So, when dialing a scope I have realized that my rifle shoots consistently high at yardages 400-1000. I know asking without any background information is only going to lead to speculation. But I need to know where to look for what is causing the difference between my ballistic calculator and point of impact. Rifle: Tikka T3 300 win mag Bullet: 215gr Hybrid VLD (.696 BC) Scope: Vortex Viper 6-20 Harris Bipod The gun is sighted in at 200 yards. 5800 feet elevation I have run the numbers through two different ballistic calculators and there is not enough difference between them to be causing the difference in POI. Things I don't know are: Is the published BC for this bullet correct? How do you measure the scope height? Possible problems: I can't find my good chronograph and had to borrow a shooting chrony from a friend and maybe it isn't as accurate as I would like it to be. . . Any suggestions? Thanks, Kelpy [/QUOTE]
