Mudcat: In your post #5 on this thread, you said:
I went ahead and ran the numbers, using the published B.C. of the 123 Scenar of .542, which seems a trifle optimistic. But never mind. With that B.C. and a MV of 2,870, in a 20 mph wind, drift at 400 yards (crosswind) is 20 inches, or 1.66 feet. Drift at 1,000 yards is 153.5 inches, or 12.79 feet.
A fair difference from the your original claim.
Just got back fom shooting in south Tx in 20-25 mph winds and it only pushed the bullet 5-feet at 1000. Nailing 12inch x 18inch plates, but I was driving the gun correctly. Basically no wind affect at all until I got past 400.
