I got one of those as well in .58!
I think I kinda like it a bit more than my CVA Mt rifle.
I'm running .562 hand cast and .020 patches with 65 gr 2F.
that load, will go thru 1 1/4 marine plywood, a 2x4, burrow under ground about 6 inches, travel 42 inch sub-terrainian and pop out, arc over a hill and go thru 24ga barn tin and bury itself in a pressure treat 2x12.
target was 50yds and barn was another 200yds beyond that.
Whumpability, ya, I'd say you own some serious momentum there!
