480 Ruger is a 475 "special", that is a misnomer, it technically a "magnum" class caliber, where as a 475 Linebaugh is a "super-magnum" class caliber, and the 480 Ruger case length is same as the 357, 41 and 44 mag case length, and the factory 480 Ruger performance is closer to the factory 475 Linebaugh that a 44 special is to a 44 mag, and you can "hotrod" the 480 Ruger to factory 475 Linebaugh performance, but that has caused difficult case extraction from what i have read about the "hotroding" the 480, and i do own a first run Ruger SRH in 480 Ruger, and the main reason the 480 Ruger didn't catch on IMHO as well as many well respected gun experts/testers honest opinions and research, is that the 460 S&W and 500 S&W stole the 480 Ruger thunder and that is perceived "Special" load of the 475 Linebaugh, which clearly it is not. i didn't mean to offend Jbar4Ranch, i just don't understand how those who have experience with the 480 Ruger, can give it the moniker of 475 "Special".
