If I was shooting long-range at foxes or coyotes , the .223 is a good choice , a .243 might be a bit better .
If I was shooting at a bear , an elk or deer , or a man , I'd take the .308
for anything over 500 yards , I'd just not take the shot .
It'd just be a waste of ammo , and it'd give my position away to someone that would prolly take a shot back at me .
Hunker down and stay hid , that's my advice .
now , having said that , if push comes to shove , and you don't have a choice , then you need to run , and run as fast and as hard as you can .
leave a few suprises as you go , large treble hooks hanging from trees slow things down , as does other things , and that's all I'm gonna say.
