In 1962, Remington Arms started manufacturing a bolt-action rifle series called the Remington 700. This model was based on the Remington 722 and Remington 721 rifles that were first released in 1948. The Remington 700 rifles use a centerfire bolt action. Their caliber determines the capacity of the internal magazine. The ammo capacity of the magazine could be 3 rounds, 4 rounds, or 5 rounds in various versions of the model. Some allow for fast unloading, thanks to their floor plate. However, not all the rifles have floor plates in them. If you want a detachable box magazine, you’ll need to order that especially with the rifle. You can find different Remington 700 versions that include their own unique calibers, stocks, and barrels.
