Has anyone here had any experience with this unusual wildcat?
I'm considering building a small single shot highly accurate rifle that can shoot out to at least 800m. The base cartridge (5.56x50R RWS Magnum) has a rim allowing me to use it in the action I have.
I've found some info on another site but in German. It lists some fairly low velocities due to it being used in slide in barrels for break action shotguns.
I have an action or 2 that will take 60,000psi all day every day.
