The early-war Japanese rifles were some tough guns. I recall reading a sotry about a man who complained about the recoil of the Japanese rifle he had rechambered to .30-06. He forgot to open up the bore, and the bolt had to be hammered open. He had managed to fire several rounds of .30-06 down a .254 bore before the gun locked up. When the action was checked, no damage was found. I have a 7.7 that my father-in-law brought back from the South Pacific. It has adjustable sights, a chrome bore, and even the dust cover, which makes me think that it was unissued. Unfortunately, the chrysanthemum is ground, so it is not in perfect condition. I have shot it enough to know that it is one accurate piece. Col. Askins was right: the only interesting gun is an accurate one.
