Killed most of my deer in bow season her in Ga....and its hot the 1st month it opens, usually the 2nd weekend in Sept.
Like steertalker said....make a good shot, and no worries. Usually you will see them go down, or hear them crash or thrash after they fall. Use a head that will put blood on the ground in case he runs into the thick stuff. And listen closely as a deer that don't know its dead usually make less noise than one that knows its hurt.
I found all my deer loosing only one, and the one I lost only got a brisket slice and lived till the next season when I killed him on the same date just a year later.
The longest I had to trail one was 80 yards...I jammed his off lower shoulder and he ran straight away running over what he didn't bounce off of, and I heard it crash. Blood was everywhere and lead me straight to where I'd heard the crash.
Had a doe feeding with here neck wrapped back around under and her head was under her body on the shot and I had no idea what happened but I heard a loud crack. She ran 70 yards and crashed. She raised here head up on the shot and when her head got level with the vitals, she too that Z 4 blade slap through the scull.
Had a few more off shoulder hits that gave 50 to 60 yard dash n crash.....and had a TON of them double lungers, where no big bone was encountered, fall inside 30, and inside 20, and I remember 3 that died within 10, and a spike that went down and crawled about 4 yards and died.
I had a heck of a recovery average that bounced around in the 30's yardage with 57 deer. Last count average I have is 38 yards after that big ten I killed November of 2007. I double lunged him, but poked his off elbow so he managed to up my average as he knew he was hit and made it 72 yards. This recovery average is on GA deer only.
The TX average is a lot different....those deer are spooky, flighty, and plumb dang crazy.....and hard as heck the hit them bottle rockets in the right place.
Anyway, I never had any meat spoil on me in GA. I think I had a rabbits foot in my pocket pretty deep.
I killed 14 deer in a row with one of those rare blue Zwickey 4 blades of the mid 80s...and brought it out of retirement a couple of year ago and took it to TX and killed a hog with it on my birthday,...then climbed up a tree and kill my Birthday Buck with another Zwickey 4 blade.
I killed 3 in 13 minutes October 17 1993, the doe I scull at shot at 7:00PM ran 70 yards, then at 7:06 I shot a 5 pointer that ran 15 yards, turned dead left and fell over after another 15....I shot him on a trot and he just kept on trotting...I really don't think he knew he was even dead as he was on a trail leading to the bean field. Then that spike came in at 7:13 and gave me an 8 yard shot and he crawled 4 yards.
Shot another doe the next hear on one side of a dogwood tree and she ran around the tree and came straight to me but she never made it. I could have spit on here from my tree stand.
I heart shot a doe once at 20 yards, she ran wide open away from me for 40 yard, fell down and flopped around a couple of times and got up and came back toward me at an angle and dove into the brush and died closer to me than the shot was....I could go on and on....
But take a good shot, and make a good shot, and all will work out great....and if you happen to have a rabbits foot deep in our pocket like I did, your trails with be short and sweet. And you wont spend a lot time following blood trails into the wee hours of the morning.
