What is the maximum shell size OR3O is compatible with?

• A. 74 mm
• B. 64 mm
• C. 54 mm
• D. 84 mm

Answer: (A)

Shell length is limited by the chamber and action of the OR3O. The system is designed to chamber and cycle shells up to a certain length; pushing a shell longer than that prevents proper chambering, can clog the action, or cause unsafe operation. Because 74 millimeters is the longest length that fits and cycles reliably, it’s the maximum size the OR3O can handle. Shorter lengths will fit, but they don’t test the upper limit, while longer lengths would not chamber.
