[quote It doesn't mean the rifle cant kill , it just means on charging very close range shots it is impossible to keep your head down on the sights resulting in misses or high shooting.it is a simple matter of geometry and physics . This has been substantiated by many big game hunters and also researched and taught by Jeff Cooper at Gunsire school.

Well, I certainly can't pit my limited experience against Jeff Cooper and "many big game hunters", but this guy was definitely charging, although not at me, and I hit him with my first shot at about ten yards. The entrance wound is clearly visible on his neck. I was aiming for his shoulder, but he evidently spied me and put on the brakes just as I shot. (I also hit him two more times on the other side when he swapped ends and retreated, plus one up his behind as he disappeared into the brush.)
