Abstract
A marking projectile configured to be fired through the barrel of a firearm having rifling formed therein is provided. The marking projectile includes a polymeric base portion configured to engage the rifling of the barrel and a polymeric front shell portion coupled to the base portion. The polymeric front shell portion has a cavity formed therein for housing a marking compound and a structure configured to deform on impact and thereby release the marking compound. The marking projectile includes a metallic annular sealing component (e.g., a crimped metal ring) configured to seal the polymeric front shell portion to the polymeric base portion.
