The body having both forward and rearward ends with a circular depression in the forward end and surrounded by an annular rim. The circular depression having a tapered bottom surface that slopes inwardly and rearwardly and terminates in the center portion in communication with a center bore that extends longitudinally along a center axis of the body. Within the circular depression are a pair of intersecting grooves that extend across the depression. The grooves have outer ends that extend from the outer edge of the rim inwardly and rearwardly across the tapered bottom surface to the center portion in communication with the center bore of the body to permit an ignition flame emerging from the center bore to move forwardly and outwardly through the grooves to the inner diameter of the bore of the barrel to ignite a propellant.
