Two setups,

My yard (grouping) : 2 hanging targets, 5 yards apart

old aluminum arrows stuck in the ground at 20/30/40/50/60 to the first target, which obviously puts them at 25/35/45/55/65 to the second. I can also shoot off my top deck
to similate the tree stand better.

My brothers yard (mostly 3d) : 2 shooting spots, 10 yards apart

from first shooting spot
woodchuck at 15
standard hanging target at 20 (sanity shot)
doe at 25
turkey at 25
buck at 25
javelina at 30
buck at 30
fox at 35 (talk about a small profile,geez)
standard hanging target at 40

back em up ten yards from the next shooting spot.

quite challenging
