1000 yards mountain hunting rifle - Seems like everything is compromise... What do I get?

[QUOTE="lancetkenyon, post: 2993101, member: 68875"] Just because a rifle is sub-moa at 100 does not mean it will be sub-moa at 1000. There are WAY more variables that will affect bullets at that distance. A 1mph shift in full value wind will push a 230 Hyb over 4" @ 1000. Misjudge speed or direction, and your groups go to hell. 10fps variation in MV will make a 2" difference in drop. Factory ammo is less that excellent with ES/SD. I have seen 40-120fps difference in a single box. That can increase drop variation to 24". With hand loads, you could help mitigate some of this if you know what you are doing. An 1/8" difference every time in hold will make 2.4" difference in POI. Can you hold 1/8" at 1000? Thickness of a reticle can make that much each time. Wind DIRECTION shifts will make not only windage, but elevation changes as well. Barrel harmonics are a real thing with velocity shifts. Even at 400 yards, can make a big difference in POI. 1K, you could easily see 12-36" in vertical dispertion. Then, there is shooter capability. [/QUOTE]
