ive done this! i waited 60 minutes and went into avery slow stalk mode with arrow nocked at 200 yards i spotted my buck he was laying but not dead. i sat for 30 more minutes and he must have smlled me or he just wanted to get up and when he stood shaky at best i put a arrow in the right spot he went 20 yards and died. upon gutting i found i shot him right acrossthe abdominal cavity muscle. not getting lungs but not gettin guts either. i might not have found him if there was not snow on the ground making him easy to track he left good blood for 40 feet and the arrow had good blood but after that it was only a drop here or there.
