If I were to say cut down a non restricted pump action shotgun's barrel for 28" to 22" would I need to notify the rcmp I did this? Could I do this myself or do I need a gunsmith to do it? I think I'm okay to do both, but best to be safe and ask first b4 Mr. Hack saw comes out to play.

:edit: also overall barrel length is measured with the chamber to as well correct?
 
Place cleaning rod in barrel with action closed. Remove and measure to verify barrel length. Mark barrel at 22 1/4". Remove barrel from shotgun. Cut barrel at marked location. Place in lathe and true up end, and get rid of any burrs, and take down to 22". Re-blue. Drill, and tap, and reinstall bead. You are over 18" so no need to inform police/CFC. You will not have a choke, or means of installing one, unless you can ream and thread inside of muzzle for tubes
 
"...Mr. Hack saw..." Do not use a hack saw. The muzzle needs to be flat and square and a hack saw won't do that. Use a pipe cutter then file off the burrs. None of that applies if there's a rib. Barrels with ribs need a smithy. Not all ribs are metal and they need to be cut in the right place. Remember that you won't have any choke after cutting 6" off.
"...notify the rcmp..." No.
"...barrel length is measured with the chamber...not sure if..." Yep. Perfectly legal as long as you don't go under 18".

A procedure I have had excellent luck with when cutting down thin shotgun barrels is to use an abrasive disc cutoff saw.

Don't laugh!

If you clamp between wood blocks, be sure the barrel is level; meaning square to the cutoff disk, and especially use light cutting pressure. Cut a little and pause. This generates little heat so doesn't affect the steel, and leaves a smooth muzzle with only a small burr easily removed.

Don't even think of calling the Fed's to tell them your private business or we'll be forced to slap ya around with a baseball bat...:)
 
"...an abrasive disc cutoff saw..." That'd work like hot dam too. I'd be thinking it being on a table with a fench. Something you'd have to have. Not an abrasive wheel in a rotary tool though. Same reason as not using a hack saw.
"...slap ya around with a baseball bat..." Hockey stick. Bats are American. Snicker.
