I know this is a subject that has been discussed before and I have gotten some sugestions. My problem is that my 7mm remington mag is spot on at 200 yards but at 600, 800, & 1,000 yards I had to hold left on the target to make a hit. I felt like what wind there was was a 6 o'clock wind and should not have made a difference in my shot. I have not yet checked the method were I shoot a series of shots at 100 yards moving my elevation turret up 5 to 10 MOA each time to track if the bullet is going off horizontal. My question is this. I do not have a scope level on my Night force 5.5x22. If i was slightly canted could it make that much difference. I am not sure if I just need more experience reading the wind or what my issue is. I am going to go out in a few days and shoot the 100 yrds changing the MOA's to see what my results are.
