When I was a small kid, I have seen game animals killed with calibers that are not considered for taking of game. I have never seen a deer walk away when takin with such a gun, or even take a step. The only time I have seen a deer run was when I was much older. A very nice buck hit in the lungs from about 150 feet ran down hill a couple of hundred yards. When we finally found this buck, it had a "smear" about 3 feet long and a foot wide. When we rolled the carcass over, the deer had about 5 ribs missing. No hart or lungs and still it ran. The bullet used was a Remington Bronze Point in a factory 30-06 loading. The previous caliber used was indeed much much smaller, and the many deer taken, never made another step when hit. I know for a fact, that if you can hit 'em where you should, they will not get away.
