yeah i understand that as well,,, when i see them in the day i use my 30.06 but that's pretty messy as it leave about a soft ball size or bigger exit wound but trust me there not going any where after that,,, after i get my suppressor ill use the 30.06 at night as it wont wake up the entire world lol
if u ever heard a 30.06 fired with a muzzle brake on it u would know why i say its far to loud
it is odd about you shot,, if placed where u say its still possible to miss the heart but even a lung shot the yote couldn't have went far.
im really not trying to be rude at all but are u sure the shot was true, im mean that's just odd cause i have dropped many with my old 10-22.
