Deer are actually getting alot smarter. When you see the herd blow out of the field, it's really because the hunter was using a plain black stock and one of the deer yelled, snorted, whatever, "He's got a gun !!!"
Actually, I've always liked the original all purpose grey, and A looks to be pretty close to that. But if I ever do one, it will probably be a fancy wood pattern. Actually though, since I hunt alone mostly, I'd be a little afraid to have an all camo rifle. I'd probably loose my bow at a 3d shoot if I didnt have someone there to point out where I layed the darn thing.
