If you're talking about a scoped rifle then the difference between the 16.5" and 12.5" are negligible on paper. You'll see more difference in barrel quality from one barrel to another. I covered this in my post. I also mentioned that short barrel .22s do not have cyclic issues with short barrels. That is a gas operated automatic issue usually stemming from the gas port being smaller for a longer barrel or having the gas port close to the muzzle making the rifle a little more ammo sensitive. Your 10/22 is a blowback action and will not be affected by a shorter barrel. A very tight match chamber will cause you grief with wrong/crappy ammo or if you don't clean it often enough. The barrel usually won't cause any other reliability issues other than problems with the chamber.
Ok ok, so as long as I'm not shooting competition I should be ok with a 12.5" barrel? It would be nice to keep the weight down. Also 12.5" don't cycle the action as we'll??
