Ok, ran into a bit of trouble today, and I was embarrassed. So, had the 25-06 shooting today out to 500 to work out some drops. Worked my way back from 100-100 yds at a time. Dead on at each until 500, where it when to total SH!T. My last shooting position was at the farm house between 2 buildings, and unbeknownst to me, there was a 8-9mph 9 to 3 cross wind about 10yds in front of me. Apparently it doesn't take a constant 500yds of 8-9mph wind to blow you off target. My question is this, how much wind can you shoot through before it matters. In this case I'd guess about 75yds worth of the bullet path was being impacted by this wind. The rest was virtually wind free or a slight headwind. I gathered that I was off of my 12in plate about 6-8in at 500 from a center hold. Elevation was on spot. Does it take 10yds of wind? 20yds? Also, if the wind had been steady 9-3 for 500yds, would it have still only drifted 2.8MOA? That was the solution from shooter app.
