looking at the picture what keeps the rounds in the mag tube when it's not in the rifle.....looks like they'd just "shoot out"![]()
The spring-loaded inner tube does not contain the rounds outside the gun. The gun is loaded with cartridges, and the spring-tube is then pressed in over the cartridges, accepting them in the process. It is then locked in by turning the flange on its base into a recess in the buttplate.
The same concept is used in modern .22 rifles such as the Browning .22 auto and the Remington Nylon 66.
