If it's a rifle I have not handled in a while I will go through it and give it a thorough wipe down and run a patch through the barrel.
If it's a regular then I just while it down and run a patch down the barrel.
I may give it a few practice shots to confirm zero
I never run a patch down mine before hunting. I verify zero then leave it dry.... tape the muzzle in inclement weather... an oiled/wet bore from a patch will change POI
