The 721 and 722 were the first "modern" Remington bolt action rifles that werer not based on amilitary design. They were designed , ifI remember correctly, by a gentleman named Mike Walker in the late 40s/early 50s. There are some that claim the 721 and 722 saved Remington from bankruptcy. They lost money on the other centerfire rifles they made, and had a very tough time competeing with Winchester and Savage.
