My main shooting buddies will absolutely not shut up about how "impractical" of a deer rifle my 20 inch AR-10 (308) with 5-30x scope is.
If I had a desire to kill a deer with it, that deer would DIE. But, uh, not exactly the point.
(Edit to elaborate/clarify: I don't have any particular desire to hunt, so I am annoyed that my friends insist on discussing the suitability of my long distance precision target rifle for hunting. That said, if I indeed did desire to hunt with it, it would be more than adequate for the task)
I'd imagine 308 out of a 20" barrel is gonna be comparable whether it's a bolty or an AR, no?
I know people who hunt deer with AR-15 in 223. Can't speak to if it's humane or effective but they get deer every year.
Yeah, it'd drop a deer to hundreds of yards readily.
(but that wasn't the point I had been intending to make; I see no need for a gun to be "practical for hunting")
