Does anyone know anything about the .510 Beck rifle cartridge? From what I understand it's basically a straight wall 308 Winchester blown out to accept .510 caliber bullets. However unless someone knows something that I don't, a 308 Winchester is smaller than .510" at its widest point so I don't see how it could be feasible. Thanks in advance for any thoughts, opinions, or answers.
