Last week on my Hunt I had a discusion with one of the guys in the group....
   The discussion was about a Deer with a well placed shot, lets say a nice double lung hit....
   I said that most Deer maybe as high as 90% would Run at least a few yards or more befor dropping, The other guy said that Most of the Deer would drop on the spot, Because "ALL" of his have....
   So lets see what the group says....Drop or Run....
   I know this would be a good "POLL" but I mess those up....  

I cast my opinion for a run & drop

i have never had a deer just drop on the spot when i hit just the lungs or heart. So im going going to say run...Curtis

Mine have always run for a bit.

run & drop....I've never had a double lunged deer drop on the spot with an arrow. 10-15 yards was my shortest.

I have also never had a deer hit in the lungs not run at least a little ways and then drop... this is with a bow. I have had several deer drop on the spot with a double lung shot out of a firearm, this is because firearms kill more from shock and bows kill from hemorrhage.

I've never seen any animal drop on spot from only a heart/lung hit, I have seen animals shot right through the heart run over a 100 yards several times. The only big game animals I have seen drop right on the spot were brain or spine shot.

Run or walk and drop. The only time they'd drop on the spot is if they were spine shot.

50 plus kills and I've had 1 buck drop with a lung/heart shot.  To this day I have no idea why it did!

I haven't shot a lot of deer but I think most will run for awhile. My first deer was shot with a 30-06 (150 bullet), the shot was a little low and broke the humorous as well as taking out the top of the heart and both lungs. Even then that little spike buck ran a good 60 or 70 yards before dropping.

I read somewhere that it is possible if a deer is exhaling when both lungs are hit that it can drop on the spot, but that seems like there's a one in a million chance of that happening.

Run

I have shot alot of deer over the years and the only one I ever had drop was a spine shot.

run until lungs give out or fill up

The closest to dropping on the spot was a double lung who jumped a bit, bit at his side then kind of hung out trying to decide what happened. He fell about 10 yards from where he was shot. The only true drop was last years spine shot. The rest have put some yardage on.

Like the others - (only gun shots have made any of mine drop and stay) Bow and Arrow kills for me have run and dropped. I did have one I shot from a tree stand that dropped on impact (like she'd been heart shot with a 30.06). She was only about 8 yards away. Needless to say, I was shocked. Then all the sudden she started spinning around on her side, in a circle on the ground, Kicking her feet and legs, while I just "gawked", with my mouth open. About the time it dawned on me to slap another arrow on my string, she jumped up and ran like a scalded rabbit. We never found her, nor any tiniest sign of a blood trail - just the arrow about 10 yards away, completely soaked with "good" blood. Never have figured that one out unless she was hit high enough that all the blood drained into the cavity. It was also witnessed by a hunter in a tree not that far the other side of her path away from the hit.

all of mine have run from a double lung shot too. may not have run far but have run.

What kind of broadhead is he using?  Where can we get them?    

run

The guy was full of crap.  Lung shot deer don't drop on the spot.

run and drop, i have had a few just walk off and thin drop.
