A ring airfoil style paintball comprises a ring airfoil carrying a visible marking agent. The marking agent is located in one more compartments in a nose portion of a body of the ring airfoil, or within one or more containers located in those compartments. The nose portion of the body of the airfoil is configured to rupture upon impacting a target, releasing the marking agent into contact with the target. Cartridges comprising a sabot containing the ring airfoil style paintball are launched from a launcher. The launcher includes a magazine for sequentially delivering cartridges for launch. A stripper associated with the launcher strips the sabot from the ring airfoil paintball, and an ejector ejects the stripped sabot from the launcher.

What is claimed is: 1. A method of marking a target with a marking agent comprising: providing a ring airfoil comprising a generally annular ring airfoil body surrounding a central passage, said body having a nose and a tail generally opposite said nose, said body defining at least one cavity located within said body, said at least one cavity containing said at least one container containing marking agent; launching said ring airfoil at a target; impacting said target with said ring airfoil; rupturing solely said body at said nose portion, whereby said cavity within said nose portion is opened; rupturing said at least one container; releasing marking agent from said at least one ruptured container into direct contact with said target, and marking said target in an area of said target corresponding to where said airfoil impacted said target. 2. The method in accordance with claim 1 including the step of rupturing said nose portion of said body at one or more stress risers located in said nose portion. 3. A method of marking a target with a marking agent comprising: providing a projectile for delivering a payload of marking agent comprising a ring airfoil comprising a generally annular ring airfoil body surrounding a central passage, said body having a nose portion and a tail portion generally opposite said nose portion, said nose portion defining at least one internal cavity enclosed by said body, which cavity contains at least one container containing marking agent; launching said projectile towards a target; impacting said nose of said body of said projectile into contact with said target; rupturing a material forming said nose of said body of said projectile, thereby opening said cavity and exposing said one or more containers containing marking agent to said target; rupturing said one or more containers containing marking agent; releasing said marking agent from said one or more containers; transferring an inertial force of said generally solid tail portion of said body to said marking agent; and imprinting said target with said marking agent in an area of said target corresponding to where said nose of said body impacted said target. 4. The method in accordance with claim 3 wherein said at least one container is annular in shape. 5. The method in accordance with claim 3 wherein said at least one container comprises a plurality of spherical containers spaced around said cavity. 6. The method in accordance with claim 3 wherein a forward-most portion of said cavity is defined by a thin wall of said nose. 7. The projectile in accordance with claim 3 wherein said thin wall includes a plurality of stress risers for causing said thin wall to rupture upon said projectile impacting a target.
