A speed-loading device for loading the multi-chamber firearm, such as a revolver, by placing the axial centerlines of the cartridges over the centerlines of the chambers in the revolver's cylinder, pulling the fingertab away; thus, rapturing the tear-off portion of the first bracket and releasing the first cartridge into the firearm. By continuously pulling the tab, the sidewalls of the second and then all remaining brackets are getting pulled further apart, their openings widen and the cartridges slide off their brackets and free-fall into their respective chambers.

An assembly for rapid loading and feeding of paintballs in a paintball marker comprises a receiver mountable on the marker, having an opening to receive and secure a magazine carrying paintballs. An ejection mechanism to clear a magazine from the opening may also be provided. The magazine comprises an outer shell that interacts with the receiver to secure the magazine, and holds an arming mechanism that is manipulated by twisting or pulling to selectively cover apertures in the outer shell to secure the paintballs within the magazine, or uncover the apertures to release the paintballs.
