RE: Distance and weight
first off, dont shoot pass your comfort range just because a deer is there. Let them walk and move your stand later!
Second, you are probably getting more KE AND Mom then most of us stickbow benders with those wheels of your and I know many who have shot game at some distances I care not speak of!
The farther out, the less room for error, and the more time for something to happen!
Get close, its what bowhunting is all about!!!
