I don't want to get in the middle of a pissing contest between you two guys, but I'd just like to post a couple of my observations from many years of hunting with scopes, open sights and reciever (peep) sights..

Open sights are VERY fast for target aquisition on fast moving targets at close range, as long as the shooter PRACTICES with them...Basically you learn to mount the gun, lock your cheek into the proper place on the stock and just look at the target and pull the trigger..Years back I killed lots of running rabbits with an open sighted Ruger 10/22 and also could regularly hit thrown aerial targets with it.. Of course I never hunted deer with it, but if I did they would be riddled with little .22 caliber holes.. Peep sights work well also.. Just ignore the aperture and look at the bead..Your eye centers ir automtically..

That said, a low power scope is also very fast, again with practice...However, fast moving targets at very close range are a real challenge with a scope, especially in dense cover... When a whitetail streaks by me at 15 or 20 yards in the puckerbrush with the smoke just rolling off his butt, I'd rather have open sights than a scope..
