This kit has just about everything needed to get started reloading. The "O" frame design creates a sturdy press for years and years of reloading. The quick change function allows standard 7/8"-14 threaded dies to be changed with the twist of a wrist. The press is made from ASTM 380 Aluminum, has 3-offset mounting holes, a 3-1/2" ram stroke and can handle cartridge lengths from the short 0.905" 25 ACP to the long 3.750" 460 Weatherby.
