I never actually personally tried a Red Dot site for any type of hunting.
Although I do have a friend who has tried the BSA brand, and they are Junk. He had it installed on his Rem 11-87, but after only 9 shots the thing actually fell apart!!! I was right there and witnessed the entire thing happen before my very eyes. I personally prefer a scope, but if I had to buy a Red Dot Optical site, it would be the Aimpoint. This is the "top of the line" brand and not cheap at all, but will hold up to anything. Our armed forces actually use this brand!!!
