i hit a buck last monday got about 8-10 inches of pentration.. found him 80 yards away.. if you think about it a deers body is maybe 18 inches thick on a good deer.. not to mention that prollyo nly 12 inches of of there chest cavity is holding vitals. if you got that much i have no doubt its a dead deer.. i hit should on my 07 buck and blood was good but stopped.. when i found him i noticed bone chucks had filled the hole
