Having seen the benefit of camo clothing I would be reluctant to say there is no benefit. If you want to get insanely close, probably it is a consideration, if you want to shoot from 75 yards or more I probably would not worry about it. That is for big game, I cannot comment on birds, as I have never hunted them. I have shot lots of game under a hundred yards, and some under 50, most of the under 50 was looking at me trying to figure out what I was. Maybe they saw my rifle.
