I reload and practice at 700-750 ft elevation. I cant rifle deer hunt in this asinine bull s--- state. I hunt in TN. at 400-450 ft elevation. When I sight in down there absolutely none of my loads are ever as accurate as at 700 ft. I think my limited notes down there 20 to 30 fps slow at that elevation. I have a mobile press ready to go this season with me to travel but I know I will not have as much time to load as I would like because when I get there all ill want to do is hunt not reload. Seems 70.8 - 71.5gr h1000 is my sweet spot with 168 vldh and cci250s 3040 fps to 3070fps You guys out west please give me some insight on what you do for major elevation change.
