Re: .308 effective hunting range
For deer and hogs, the 308 can be effective out to 600 yards with a well placed shot. Both Hornady and Sierra has good hunting bullet options in the 165+ weight class. For Sierra look at the 165 and 180grain Game Kings. For Hornady, they look at their Interlock and Interbond bullets (available in 165+) and avoid the tipped bullets like the SST. When shooting at hogs, you want a tough bullet that will punch through the shoulder blade.
I'm not gonna shoot here. I'm gonna shoot waaaaaaaay over there!
