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.
