I would say 10 or 12 seconds on a double lung hit,of course they can cover a lot of
ground in that length of time.100 yards easily,Single lung ,they can live a good long while, lung /heart , they die very quick also.
Liver /lung will put them down very quick also and they usuall don't travel as far. Of course these are just general rules,seems every one is a little different depending on the deers demeanor at the time of the shot.
