Troy I don't know.....but I'm guessing (PURE Guess) I'd drop 10 points or more. Heck it could be more.
This is what I'd say I lost from shooting outside, maybe a bit more. It was pretty windy and I had to hold much longer, or tryto time a larger weave.
This week I plan to stand inside an unheated room and shoot out the doorway to a target. Won't take care of the cold, but will block the wind.
(and if anyone is worried about safety, the doorway is completely windowed the entire length of theroom on both sides so no one can walk in front of it without me seeing)
