Actually, the 98 Mauser is considered the sturdiest of the Mauser family (cock-on-opening, plentiful camming action for extraction, beefy front ring diameter, etc), although Ackley was basically unable to destroy a Jap Arisaka action with blue-pill loads. He succeeded in blowing the barrel out of the action, but that was about the worst of it. The Arisaka is considered a cousin to the Mauser, as is the Pattern 14 and U.S. 1917 Enfield. The U.S. Springfield is a hybrid of the small-ring Spanish Mauser and U.S. Krag rifles, NOT the large-ring 98 Mauser.
