lI picked up a little Remington semi 22.The barrel has 22 shorts longs and long rifle on the barrel,but only the shorts will work.I checked the chamber and you can see a lip inside I checked the end of the barrel and it looks like some work has been done to blend in a liner .It looks like who ever put the liner in did not have one long enough.My question is can a reamer be used to take out the lip in the chamber to take long rifle ammo
