Ok after hearing this one that one its too small, oh yeah shot placement means not a thing with that caliber. So I go to thinking just for fun I took out my Henry lever action 22lr and shot at some 223 cases sitting on the shelf of my range. I layed them on their side and shot at the base of them from about 75 feet a way. What shocked me more than me actually hitting the cases was the fact that the little 22lr drove the 223 case all the way into the back board of my shelf which is made of two layers of 1/2 hardwood! Not that I expect the hardwood to serve as a back stop as it is just there built into the front of the berm so that I can set things up on the shelf and have them stay put for targer practice. But Still it got me to thinking that there must be a lot of arm chair quarterbacking going on about this or that caliber.
