RE: 40 yard shot
I've been shooting bows for 42 years,Use to kill groundhog at 40yards when I was 20.
I can shoot 3 inches from center of bulleyes at 60 yards,but I have never shot a deer At more than 25 yards.There is too many things that can get in between,like a twig,a sudden wind ,noise bad position ,deer mooving etc.
It is irrespect to the fauna for shooting that far.If you want to kill unethical and without respect for the animal,you should not be in the wood anymore.Go in a deer farm and take a stick of dynamite ,that is what you think hunting is .But fellow hunting is to bring in deers to 10 feets and then smile at them and wait for the criiter of your choice.
