Shotguns are not cheap and when you come to a need to change out the choke, clean the old lube out of the tube and use Gun Snot® Paste which acts as an anti-seize coating on the choke.

The second issue when you are out hunting (or maybe practice) is you want to make sure that all the external blued surfaces are coated in case rain comes in the middle of the shoot – you are protected from flash rusting and in the barrels, after you cleaned the barrel with your favorite cleaner – then chase the barrels with a couple of swabs with Booger Buster to protect them of oxidation.
