Welcome @fulldraw!

I'm starting to use ground blinds more and more - more so than treestands now. So this is an area of concern for me. I've shot through the mesh on my blind windows many times to make sure this is not a problem. I am finding it isn't with my Ameristep Doghouse or my Big Game Groundmax Escape Deluxe.

But the first time or two I shot out of either this year, I found I was off a little for the reason mnsqueeze gave. Its a very different feeling inside the blind and looking through mesh at your target. So you need to get used to that and adjust. Basically, don't get discouraged if you're off a few inches at first. Get relaxed inside the blind and keep focusing on the target.

I offer this final caveat. I can't tell you for certain if the mesh affects arrow flight. I would have to think it does slightly in terms of a few milimeters or whatever, but I havent' seen any conclusive research or tests done by the blind companies that offer any evidence. I say its just a matter of trial and error of figuring it outon your own.

Oh, and for those who say, that's why I'd never shoot out of a pop-up blind. If your arrow is off by a few milimeters, or an inch or two at most, let me ask you, is that still close enough to make a clean kill shot? I'd says so.
