I had an AR-50, left handed bolt, when i was living in Idaho. It was a lot of fun. We'd set up targets up high on ridges, and hike a few hours to the next mountain over, and then send rounds across the valley. Gallon jugs of water were great reactive targets. They are physically very big and heavy and loud; my shoulder could only take 10-20 shots at a session; and then the ammo cost... but nothing else goes those distances with that accuracy! (..well, maybe 20mm....)
I sold mine when i moved back East, because there's nowhere in CT I can find distance for one...and too much loot to have tied up in something without a use. I can't even find a range to see the full potential of my .243 -
Hatterasguy, I take it you don't want to be that guy on the 50-yd line knocking over the next shooters' bench, either? haha.
