What kind of idot shoots game at 2000 yards?
The purpose of hunting is to kill the animal as quickly as possible, preferably instantly. For game the size of deer (man sized/weight) the acceptable striking force is 1000 foot pounds (thats why many states prohibit the .22 centerfires for deer). Nothing, apart from maybe a .50 bmg carries that much energy that far. Additionally it is ludicrous to think that you could even hold well enough to hit something at that distance in field conditions, not even considering wind deflection (6-12 FEET with a 5-10 mph wind).
Hell the world record BENCHREST group is over 5 inches at 1000 yards, and thats with a 60 pound rifle.
Anyone who claims to have shot game at this distance either hasn't the faintest idea how to gauge distance or is feeding you a line of B**S***. Either way keep him the hell away from me, I don't play well with immoral idiots.
