The 722 and the 721 were the first center fire rifle Remington made when they resumed commercial production after World War II. The 722 was chambered in 222,222 magnum, 243, 244, 257 Roberts, and 300 Savage. It became the model 700 with some minor cosmetic changes. There was nothing wrong with the rifle, there are still a lot of them in service, I prefer them to the 700, just in my opinion. As a side note, they were the first of the round reciever welded recoil lug actions to be made.
