Has anyone used the Harvester .50 caliber Red ("Smokless Powder")Crush Rib sabots in anything other than a Savage with smokless powder? Sabotloader's picture chart shows them at .508 diameter when loaded with a .452 bullet.I suspect I could load them in my loose barrel Mustang with my favorite 300 grain Gold Dots, because the GDs load pretty easily with hph-24's.
