Hello I was just wondering why tool steelcartridge cases aren't used more with close to limitless reloading capabilitiesas the 338 Yellow Bastard is the only rifle cartridge that uses tool steelinstead of brass as the material for its cartridge cases? I was also wonderingif tool steel is used for the cartridge case how much higher than SAAMI specscould you go(?) as I want to use a tool steel 308 Winchester / 7.62x51 NATO for use in a FAL with the velocities of a 30-06 or even a 30-378 Weatherby is this possible (?) I do realize it would be like a 308 Winchester +P+++++ (?) could using this type of case take some of the pressure of the action of whatever is firing the round (?) Any answers or thought would be much appreciated.
