Yes that is 100% normal with 10/22's. It is not a defect in your gun. It's just an occasional pain in the ars. That A&B barrel is manufactured by Green Mountain Barrel Company and comes with a Bentz chamber - which is a match chamber specifically for semi autos.
I have a bunch of GM barrels and I recommend a good break in procedure. Fire 5 rounds, clean repeat for 100, then 10, clean and repeat for another couple hundred. For cleaning I never use a rod because of the inability to access the breech end. I use an Otis or Patchworm: Wet patch, two dry patches, done. Just make sure the patches are good and snug. a brush on the chamber area during this break in will ensure maximum smoothness.
After every extended shooting session I do make sure the chamber area is very clean as well as the bolt/receiver.
FYI I don't use oil on the moving parts anymore... I use a dry lube. Available at any Home Depot, auto parts, etc.
