Abstract
An ammunition case reloading press is based on an O-frame die cast from a low strength metal. A case carrying ram is driven reciprocably through a bottom member of the O-frame toward and away from a die in a top member. A compound lever system is actuated by a manual operating arm to drive the ram. A stop prohibits the links of the lever system from toggling into dead center position to thereby limit the stress of the O-frame. The operating arm is designed so it will flex to signal the user that unnecessarily great resistance is being offered and that the die should be adjusted relative to the ram to reduce the stress. The operating arm and lever system pivots are askew to a vertical plane passing through the frame so the arm swings clear past the side of the O-frame and so there is a clearer line of sight to the opening in the O-frame where the cases are placed on and removed from the ram.
