Going on my first western rifle hunt in 2 weeks for mule deer. I’ll first off admit I’m more of a archery guy so this longer range shooting is all new to me. Here in VA your lucky to get 100 yard shot in the places I hunt. For this hunt I upgraded scopes and got a 4x12 cds for my 30-06. I plan on limiting myself to 300 yards since this is all new. I shot a few weeks ago with the dial that comes on the scope and was happy with the groups. I’m zeroed at 100 and it was 7 clicks for 200 and 18 for 300. 165 grain Hornady sst. I ordered my custom dial for the elevation in CO I will be hunting. 8000ft 40deg. Here in VA I’m at 2000ft. When I put my dial on today I checked to see if the clicks were close and it’s only 5 clicks for the 200 mark and 13 for 300. Does the elevation make that much of a difference? Thanks
