Yep made right here in Michigan.

Sure, it's a wildcat & exotic design and there may be some folks that find benefit with a longer range capable ML. Who I don't know but there may be some. Folks that want the longer range capability or are restricted from using centerfires and wish for longer ranges. Some folks would also prefer a custom rifle.
Hey, if I had cash to toss around I might want one!

It's not that far out or difficult to over-build a weapon to allow powder charges beyond 150 BP.

4 Pellets are equivelant to 170gr black powder. So the power capability is not that far over the 150gr Magnum ML's.

The testing claim to 125K breech PSI is impressive. I'd be curious to see the test details.

If it floats your boat then it's made right here in the usa.
