Shot Shell Roll Crimp Tool

Roll crimped shells give you improved performance for almost every load type. Roll crimps provide consistent closure resistance, delivering ultra-consistent chamber pressures. Large pellets, heavy payloads and custom hull lengths are just a couple specific component advantages associated with roll crimping. Roll crimped loads are easy to make - once you have the right tools. Roll crimps are applied with a special machined bit which, through a combination of heat and pressure, folds the last 1/4" of a hull inward and down - until the leading edge contacts an overshot card sitting on top of the payload.

• Start with any uncrimped hull. New, uncrimped hulls are available in many types and sizes. Once-fired hulls can be cut down 1/4" - a 3-inch hull can be cut down to a 2-3/4" length then roll crimped. Likewise, a 2-3/4" hull can be made into a 2-1/2" hull for custom upland or target loads.
• Load the shell as you would any other.
• Place a .030" overshot card on top of the pellet charge.
• Secure the hull. Though it does not take much force to hold the shell, securing the shell is easiest with the help of a Hull Vise.
• Place the roll crimp tool on top of the hull (making sure it is turning clockwise as you look down from the back). Start the drill spinning and apply very light pressure. When the edge becomes pliable through a combination of heat and pressure, roll the lip down until it makes contact with the overshot card wad.

Available in .410, 12g and 10g
