Why do you want it ported?
So does the extended ported tactical Rem choke and a Magpul SGA stock with Rem Supercell pad, from my experience and use.The ported barrels on my 500 seem to greatly reduce felt recoil and percussion as well as muzzle climb.
Ported barrels do reduce felt recoil and muzzle jump, but they aren't made by Remington. Don't think there's a 22" either. You'll have to have a regular barrel cut, ported and changeable chokes installed if you want that.
Porting doesn't really do much for a hunting gun though. You're not shooting it as often as say an IPSC/IDPA player does.
