[QUOTE="abinok, post: 117148, member: 16"] Its been a while since ive seen those charts! Years in fact! These are very common in the smallbore (rimfire) 3position rifle world, and the effect is observable, but not completly consistant across all rifles with all ammo... or at all ranges for that matter. shooting only a very, very few rounds of 22rf at 100yds on a windy day will show you that this stuff happens. How much and to what extent however, is something you have to learn yourself. Just for referance... and since this is LRH... my 220SMK load takes 2 MOA less elevation in a 10mph wind from the east (right) than it does from the west (left) at 1350... and thats allowing 1 MOA for the differances in air density due to temp changes.
