I have owned three belted magnum cartridge guns. Two 300 Weatherby and one 270 Weatherby magnums. One was a Winchester chambered in 300 Weatherby. On all my rifles I had to buy new brass after about three reloadings or buy a special die for pushing the belt back. Back then new brass was expensive and if I remember correctly the die was custom (really expensive). The jist of the article was about weather it could make a come back Not weather it was a good cartridge.
