What is the .499 LWR cartridge? Was playing
Around with the Magnum Research custom builder and saw that available as a chambering.
I'm sure sor special states that require
straight walled rifle cartridges to be allowed in the hunting field. Dave Manson had one built up on his design (Ultra Mag case) on a Remington M7 custom in .510 caliber! He lives in Michigan and that's what they are restricted to, straight wall cases under a certain length.
