Jimmy, I was just pulling your chain about the faux sniper business.

I enjoy the long distance shooting, too. Anyone can shoot a bulls eye on an indoor range, but when it comes to reliably hitting a mansized target at a thousand yards in natural terrain, not everyone can do it. When I went through basic training in 1965 at Ft. Jackson, I hit every 350 meter target but got "buck fever" and pull off a shot at a 50 meter target using the M-14. (embarrassing as hell).

Of course, it was "on the clock" shooting, too. We only had seconds to identify which target came up, aim, and fire. The targets were set at 50 m., 100m, 150m, 200m, 250m, and 350m, on hilly, natural terrain. A lot of fun using that peepsight on those.
The NATO round is the 5.56 mm (.223 cal.) The .308 is a 7.62mm. I worked with the minigun that uses the 7.62 rounds and was told it was the same as the Winchester .308 cal. Sooooo, if you had access to military surplus 7.62 ball ammo, you'll be able to build up a supply of "fun" shooting ammo.
Check out the dealer named
Cheaper Than Dirt. You'll find a lot of interesting equipment buys as well as ammo. They're based in Texas, I think and they do have a website by that same name.
Just have fun, and stock up on plenty of ammo before the government decides to tack a humongous excise tax on it.
