Sounds more like a Barrett .50 sniper rifle. 25+ pounds, with a muzzle break as big as a brick bat. I've shot one. Shooting at an 8" plate at 1000 yards. And you can reliably hit it. But a sure-kill requires 8" accuracy and beyond 1000 yards, it gets _very_ dicey. With wind or mirage you can forget it. A machine gun is a different animal. Hosing someone down at 2500 yards is far easier than placing a single shot on target. > >>was a little scary. Nice skill to have if you need it, but it scares me when >>people fantasize about it.
