As I said before this is now to me. I have been shooting the heck out of arrows lately from 20, 30, 40 ,50 yds. from the ground straight on with great grouping. I will be hunting out of a stand I'm guessing 12' - 16' when I get one. How much difference will my shooting be and how important is it to sight in elevated now that I will be actually hunting that way. Without setting up the stand somewhere outside the woods how is the best way to get sighted in???

do you have a deck, alot of people shoot off that, also 20yd straight shot is different then a 20yd shot in a 12-16 foot high tree, it would be something like 23-24 yars if I am correct...

if you bend at the waist and shoot with the same anchor points you should hit the same as you would from the ground.

for most typical bowhunting, i think most guys shoot the range of the target from the base of the tree to the target. within 30yds or so you might be off a yard or 2...i cant remember the real numbers but its nothing to worry about...

definently PRACTICE it though. its a little different and can feel akward. i had to get used to shooting with my feet so close and bending at the waist etc. shooting with my buddies at a 3d shoot today, the last target was a treestand shot. you could tell who didnt bend at their waist...

Yes you should definately practice from an elevated position, I use my deck. Just use your same pin as you would on the groundand see if it hits where it is suposed to, if not then adjust accordingly.
