i just shot a very nice buck. at least a 5x5 and maybe a drop tyne. think i hit a liver. how much penetration do you all think is needed for a sure kill? i sat in my stand for 2 hours and watched him bed down after the shot and he never moved. i left the timber at dark and will go back in the morning praying he's dead. my worry is that it didn't look like i got enough penetration. think i hit an inch or two ahead of center of his body. what say ye hunters-will he be dead tomorrow, or am i screwed?
