I had an 85% hit rate for 60 targets at a SRM with constant 23mph winds, sideways snow, and high temperature of 23 degrees.
OK, so.......congrats? If you've got $10,000 to risk..........and if I put you on a 190"er and you miss or wound, you owe me $15,000. You will not have a bench, terrain likely won't allow prone. Possibly sitting with a bipod/sticks, or standing off sticks.
You likely won't encounter "constant" wind here.
