Those who shoot may find this of interest. Those who think that shooting is akin to murdering cartridges may want to avert their eyes.
Most cartridge collectors are familiar with the 8-round enbloc cips for the U.S.Rifle Cal .30 M1. But there are at least two other clips commonly used by competitors and hunters.
The first holds 2 rounds and is used in the rapid fire stages of hi-power matches. The two shots are followed by loading a full clip of 8 to complete the 10-round rapid fire stage.
The 5-round clip is used by hunters in States where a rifle cannot hold more than 5 shots.
Neither clip is an absolute necessity. It is possible to load any number of rounds (up to 8) using the standard enbloc although it does take some manual dexterity and some tough fingers if the bolt decides to slam shut while you are fumbling to load a partially filled clip.
