Abstract: The elongated vented gun barrel may be used with a conventional firearm such as a shotgun or rifle. Strategically placed vents or ports may be placed along the length of the elongated gun barrel which function to slowly bleed off high pressure gasses within the elongated gun barrel following discharge of the firearm. The vents or ports facilitate the discharge of high pressure gasses at a controlled rate to reduce the report of a firearm. The gradual release of the high pressure gasses minimizes the shockwave following discharge from the conventional firearm.

Abstract: A rotary trimmer apparatus and signature trimming method are provided that enable operators to set a gap spacing between a rotating knife and an anvil at different predetermined sizes in an easy and accurate manner. The operator chooses the optimum knife/anvil spacing that produces a scissors-like cutting action on the particular type of signatures being trim cut and which does not cause premature knife dulling.
