An arrow saw includes a blade misting arrangement that provides for control and removal of carbon particulate. The arrow saw includes a base with a mounted motorized saw and an arrow tip support that supports the tip of the archery arrow while cutting. The saw includes a hood enclosing the blade with a misting nozzle for generating a mist within the hood during cutting operations. The mist captures particulate generated during the cutting operation and a vacuum system is connected to the hood to remove the wetted particulate. The arrow saw also has a pressurized water supply inlet coupled to a misting nozzle on the hood for providing a source of pressurized water to the misting nozzle.

A bullet seating die for use with an ammunition press to seat a bullet in a case includes a die housing having an ammunition press mount for mounting the bullet seating die on the ammunition press. The die housing defines a bullet receiving space having an open end and a side window in communication with the bullet receiving space. The side window sized and shaped to permit the bullet to be inserted therethrough to position the bullet in the bullet receiving space. A seating stem is supported by the die housing. The seating stem is arranged to engage the bullet to press the bullet into the case when the ammunition press is operated. A spring biases the seating stem away from the open end of the bullet receiving space to permit the bullet to be inserted through the side window and into the bullet receiving space.

Manufacturing capsules, comprising preparing a first and a second capsule element, at least the first element containing a cavity, each element, being provided with a peripheral ring, bringing the elements together, so that the rings are superimposed, placing the two elements between a sonotrode and an anvil, the anvil containing an anvil recess and a striking surface, surrounding the anvil recess, the sonotrode including a sonotrode recess, with the same cross-section as the anvil recess, and a working surface surrounding the sonotrode recess, wherein the striking and working surfaces are configures to come into contact with each other on a working area, extending around the recesses, clamping the rings between the working surface and the striking surface by the proximity of a sonotrode and the anvil, activating the sonotrode and directing the ultrasound towards the anvil, whilst maintaining the clamping action, wherein the rings are detached from the capsule.

A non-jacketed expandable bullet including a monolithic sintered body. The monolithic sintered body includes a base portion and a deformed hollow nose portion extending distally from a distal end of the base portion. Also, a method of manufacturing a non-jacketed expandable bullet including providing a monolithic sintered body including a base portion and a hollow peripheral portion extending distally from a distal end of the base portion and forming the hollow peripheral portion into the shape of a hollow tapered nose.

This invention relates to a method and apparatus for recycling plastics, electronics, munitions or propellants. In particular, the method comprises reacting a feed stock with a molten aluminum or aluminum alloy bath. The apparatus includes a reaction vessel for carrying out the reaction, as well as other equipment necessary for capturing and removing the reaction products. Further, the process can be used to cogenerate electricity using the excess heat generated by the process.

The present invention provides a subsonic ammunition cartridge including a polymeric casing body comprising a generally cylindrical hollow polymer body having a body base at a first end thereof and a mouth at a second end to define a propellant chamber; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber, wherein the propellant chamber has an internal volume that is between 25 and 80% less than the open internal volume of a standard casing of equivalent caliber; and a primer insert positioned at the body base and in communication with the propellant chamber.

A method is disclosed for modifying pre-existing ammunition projectile (10) which includes a hard metal inner core (11). The projectile is secured and a drill is applied to the tip end (17) of the projectile so as to create a bore (20) extending into the core. An insert (22) is then coupled to the projectile. The insert may include a shaft portion (23) which extends into the core channel and a tip portion (25). The insert is made of a non-hard metal or soft material.
