Let's face bullets can skip and riccochet off of virtually anything in it's flight path and the person pulling the trigger is totaly responsible for everywhere that bullet goes and every destructive thing that bullet does until it stops.I personally wouldn't shoot an big game animal swimming across a lake or swamp but at the same time if I saw a legal big game animal standing at the far edge of a swamp I wouldn't think twice about weather or not it just crossed or even how far it travelled to cross.If gave myself the ok to kill that animal, I'd point my rifle in the direction of the target aim at the vitals and pull the trigger. I do it in a heart beat.With no regretts as where that animal just came from or how far it travelled.
I consider myself an ethical hunter for the most part
but if I worried about steep climbs valleys water these animals endure on a daily basis and took that into consideration I wouldn't have killed
a single animal by now.
And every hunter would think Im a PETA supporter.
