A large capacity magazine apparatus for spherical projectiles, such as toy foam balls that may be used in conjunction with a launcher. The magazine includes drum and clip housings and a rotatable sprocket with longitudinal flutes that together form a smooth pathway for the foam balls to travel in the magazine and to alleviate jams. The smooth pathway includes a helical path, a transition path and a linear path within the housings. A constant force spring provides a rotational force for the sprocket and a plurality of articulated rigid balls function to push the foam balls out of the magazine and into a firing chamber of the launcher.

A cased telescoped cartridge that includes a cylindrical case surrounding a projectile, a front end through which the projectile exits when the cased telescoped cartridge is fired, and a thermal protective insert located at the front end. The thermal protective insert insulates the cased telescoped cartridge from heat emanating from a barrel of a firearm into a chamber of a firearm when the cartridge is loaded into the chamber of the firearm. The thermal protective insert is made up of at least one thermally insulating material, and is integrated into the front end of the cased telescoped cartridge.

Provided is a detachable drum ammunition magazine for rimmed cartridges having a housing with a neck portion configured for detachable attachment to a firearm. A first sprocket in the housing has a first axis of rotation. A second sprocket within the first sprocket has an axis of rotation concentric with the first axis of rotation. The first sprocket has a gap through which cartridges are pushed to the neck portion and a hinged follower is on the second sprocket.

The invention is an improvement to a typical firearm drum magazine cartridge feeding system. The improvement provides firearm drum magazine feeding systems with features that work together in tandem to actuate a typical firearm bolt catch. The firearm bolt catch is a common feature in many firearms with the purpose of halting the forward momentum of a firearm bolt. By actuating the firearm bolt catch, a firearm operator is aware that a drum magazine is empty of firearm cartridges. The advantage of this improvement is twofold. First, a firearm enthusiast or soldier utilizing a drum magazine with this improvement will enjoy the benefit of not taking an additional step to pull back a firearm bolt before reloading, and any person will enjoy the added safety benefit of knowing when a firearm is unloaded and safe to handle.
