[QUOTE="cohunt, post: 1641472, member: 94491"] all your shots and poi will be different in CO-- you are going from 900ish msl to probably around 10000msl (where most elk hunting takes place-- you will need to not only site in your rifle at altitude when you get here, but all your drop chart info will change due to the higher altitude/less pressure and most likely less humidity too. best to find a range to check your zero and drops when you get here (dont forget to bring extra ammo) as others have said, if the poi shift is due to a barrel heat/harmonics issue, it may be repeatable, if its from higher velocity then the extra altitude will extrapolate the problem best best, since you are using RL26, is to just send all the rest of your reloder 26 powder to me here in CO and I can use it for testing purposes ;) [/QUOTE]
