Yes, I want to dress up that turd of a gun and try some long range paper punching. Considering that the round is to 50BMG what 243 is to 223, and the difference between 400 meter and 1000 meter sights is negligible, it should made a hell of a LR rifle when properly scoped due to flat trajectory.
Other modifications will include drilling a hole in the butt for a cleaning rod and manufacturing a better butt pad. The role of the new brake is to reduce recoil to exactly the rate at which the action will just eject. Maybe crowning is a good idea, don't know have to check and see. And all those changes will have to be reversible in order to be able to put her back to the original configuration.
