This is quite an accomplishment.

Interesting design the rifle has with a water jacket.
Benchrest shooting reminds me of drag racing, it's not too practical but still neat.

You think his stock is rigid enough? I guarantee some of these guys would mount it on a trailer and pull it to a ground blind at the edge of a nice big field.

I'd be lucky to hit a barn at 1000 yards.

Shot some 1000 meter ranges, with great results, in Scout/Sniper school, back when I wore a younger man's clothes. These days, if I can drop my rifle and hit the ground with it, that's a win!
