Lyman Collar Button Rifle Bullet Mould, 45 Caliber, 45-70 Double Cavity

The Lyman Collar Button Rifle Bullet Mould is made from solid leaded-steel and machined to an exact and smooth super fine finish. The Mould is then heat treated (that is why they are blue in color) and features hardened steel alignment pins to provide many years of bullet casting service. Sprue plates are made from solid steel, ground flat and held tightly in place with tempered steel spring washers and screws. In addition, break-in is often half the time required for iron mould.
