Yes, I shot one a year or so back and was able to hit accurately at about 400 yards. But I only shot it once...

The recoil wasn't that bad (it had an enormous muzzle-break) but after I shot it, I tried to cycle the bolt open and couldn't.

The guy that owned it (friend of a friend) said "Oh yea, you have to hammer the bolt open with a heavy object." Then he took a rock and did such.

He was shooting - what he claimed - was military surplus ammo.

I tried to explain to him that this fact, along with the heavily cratered primers, were indications of excessive pressure and that he shouldn't shoot the ammo anymore.

Well, not only did he think that he knew better - and although I can't speak to his genitalia - he seemed to fit the bill as imply and obviously had more money than sense!

And I suspect that he's still shooting it...

And hammering the bolt open with rocks...

Apparently Darwinism does exist...
