ABSTRACT:
A pattern controller has a disc-like adjuster which can be snugly fitted in a case and a plurality of stays which integrally project in the axial direction from the adjuster. The adjuster is provided with a tapered surface adjacent to the stays to define a guide surface for shot and a center hole through which shot passes. The stays are inserted in the shot charged in the case, so that the adjuster surrounds the shot. The case is crimped to complete a shotshell. The pattern controller provides a concentrated-type shotshell or a scatter-type shotshell. When the shotshell is fired from a skeet choked barrel or an improved cylinder barrel, a remarkably concentrated or scattered pattern can be obtained. A ultra scattering type of pattern controller which has no center hole is also disclosed.
