Abstract: A drill core sample holder that receives drill core samples therein, has a lower housing formed as a unitary structure of plastic material that defines a plurality of lower channels therein and an upper housing formed as a unitary structure of plastic material that defines a plurality of upper channels therein. The upper housing is adapted to be mounted onto the lower housing in a mounted position in which each lower channel is aligned with a respective one of the upper channels so that the lower channel and the respective upper channel collectively define a tubular receptacle for containing a respective drill core sample therein.

Abstract: A projectile including a spherical core and a hook or loop outer cover, has an overall diameter, including the cover which is equal to or less than an internal diameter of a 68 caliber paintball gun for use in the gun in place of paintballs. The diameter of the projectile permits gravity fed, drop loading of projectiles into a conventional paintball gun barrel without an compression of the projectile being required whatsoever. The resultant small gap surrounding the projectile within the barrel permits some pressurized gas to escape around the projectile when firing, thus limiting the velocity of the projectile to a safer velocity for closer range use of conventional paintball guns. A gun is also described having a shuttle for pushing a projectile through the barrel thereof by action of a stretched resilient band. The barrel is sized similarly to a conventional 68 caliber paintball gun for firing either paintballs or the projectiles described herein.

Abstract: A target device is worn by a user in a game comprising projectiles covered with either hook or loop fasteners. The device includes a supporting element for being supported on the user which carries target panels having a target surface covered with hook or loop fasteners for mating connection with the projectiles. The target surface has an irregular in contour comprising various raised protrusions formed of resilient material. The irregular contour of the target surface results in a surface which lies at various angles, thus increasing the likelihood of a shot from any direction being perpendicular to a portion of the target surface for better attachment of the projectiles to the target surface in a hook and loop type game. The resilient nature of the protrusions also absorbs some of the impact force of the projectiles to reduce the tendency for the projectiles to bounce off of the target surface.
