Does the Governor of Virginia think of is? South of Roanoke we all hunt with High Powered Rifles.
Hunters make the best snipers. !
This question begins with the assumption that hunters always do make the best snipers which is a separate debate. For the sake of argument though, let's go with the assumption and figure out why that might be true:
Familiarity with the tools of the trade. On average, a hunter is more likely to be familiar with precision rifles. They are more likely to know which calibers are best for the differing game and which rifles make the best delivery systems. They probably also understand ballistics and maybe even practice reloading their own ammunition so they know details about the mechanics of shooting that the average soldier doesn't.
Practice. They've probably spent more time shooting on their own instead of just a military range day. The more you shoot, the better shot you'll be.
Stalking. A good hunter knows how the quarry thinks and operates. Humans are animals too and tend to mimic some behavioral patterns found in animals. A good hunter knows how to spot those patterns and anticipate them in order to be at the right location at the right time to take the shot. They're also likely to be more patient which can be necessary for a military targeting situation.
Nerve control. Every hunter knows what it's like to get "buck fever," that adrenaline dump that comes when your target unexpectedly shows up right in front of you ready for your shot. Now amplify that a thousand times and you might barely begin to understand the adrenal dump of combat. Having some practice in controlling those nerves could make the difference between success or failure/life or death.
Of course, the military can train anyone to these standards, but training someone who already has a familiarity and a knack is more effective than starting someone off from scratch. (Think about it before trying to take our Guns)
