A reloading system and method for reloading cartridges into an ammunition magazine. The reloading system has a storage container for holding a supply of cartridges. The internal chamber supplies a set number of cartridges to a loading chamber. A first spring-loaded plunger extends into the loading chamber from a first end. The first spring loaded plunger biases the set number of cartridges in the loading chamber toward the second end. A magazine receptacle is offset from the second end of the loading chamber. A second spring loaded plunger is provided that extends into the loading chamber proximate the second end. The second spring loaded plunger advances one of the cartridges from the loading chamber into the ammunition magazine that is engaged with the magazine receptacle. A new cartridge is loaded each time the second spring loaded plunger is manually advanced.
