Some of you may remember the thread I started about the minimum distance to sight in a rifle. Well, this past Saturday I took the M-77 Hawkeye to the range for the first time in her young life. I decided to go to the range instead of my father-in-law's farm due to the fact that he doesn't have any benches to rest on or target stands. Anyway, the public range I went to is on the side of a mountain (= windy) and the target areas are uphill from the benches (the 100 and 150yd targets are REALLY uphill at a sharp angle, again it's the side of a mountain).

The ole girl shot well for her first time. After some adjustment she was shooting an inch group, 1.5" high at 100yds. For me that's fine since I'll only really be hunting with the rifle and the margin for error on a deer is a lot bigger than 1". However, I would like to get her shooting at her best and I'm wondering if trying to sight her in, at a sharp angle, on a windy mountain side is the best idea. I mean, now that I've got her fairly well zeroed, I'm comfortable going to the farm and setting out some sand bags (probably what I should have done to begin with). Does a sharp angle like at the range have any real effect on the bullet, or is it so marginal that I wouldn't be able to tell the difference?
 
Shooting uphill or downhill sharply will make you shoot high. So I would not be surprised if when you shoot in the flat land you are right now pretty much dead on at 100 yds (or maybe even low). The wind has to be over 10mph cross wind to have any real effect at 100 yds.
What was the caliber again? If it were me I would sight in very close to 1.5" high at 200 yds with no wind in a flat area. That would put you "in the money" out to around 300 yds.
