Why some 22 rifles can shoot shorts, longs ,long rifle

[Hawkeye6]

Probably the magazine. All three of htese rounds are a diferent length. the shroter ownes will probably not feed in the rotary magazine fo the 10/22 but will through the tubular magazine of your old rifle.

I had an old tube-fed Winchester pump rifle that said the same thing. My Dad told me not to use shrots or longs as it would foul up the chamber.

Besides, can you even find shorts or longs nowdays?
