Chuck a cleaning rod into a cordless drill with a brush with wisps of 0000 ( 4 aught) steel wool -or- the finest grit of Scotchbrite pad.
Leave choke tubes in.
Run from chamber to muzzle and done.
--
Most failures are chamber related, so we kept a rod and cordless drill handy at the range.
Also kept handy was just the rod and doing this by hand as WE did back in the day before cordless drills
Plus - we took a cleaning rod and bent one to fit a chamber and used with out removing the barrel.
Some guns one cannot remove the barrel....like J.C.Higgens.
Cleaning:
We did not have time to clean , as we were too busy shooting, or reloading, or traveling to shoot, or shooting practice rounds, or competing.
You shoot 8 practice round of skeet a day, min (200 rds) or as much as 2000 rds in a week, and see how often you break down a gun as so many do.
Run 20K, 30K or more round a year through a shotgun.
Inspect & Maintain ...
Clean chamber, extraction and good to go.
When screw in chokes came to be, just remove, wipe off, apply RIG + P , screw back in to "finger tight snug".
If a 1974 Win SX1 , Beretta 303, can go 5000 rounds with just cleaning chamber and extraction...
If a Browning B-80, Winchester 1400, Rem 1100 can go 2500- 3000 rds with just cleaning chamber and extraction.
Using Browning Gun Oil from a tin can ...
Surely these new guns can do this?
Before some ask, one SX1 was retired , still ran like a top with 300,000 rds.
The other guns mentioned above, have high round counts of 100,000 or more.
I mean, if these "old antiquated guns" could do this with "not being taken care of " and maintained with "out of date cleaning and lube products", new and fangled gun with super duper cleaner and lubes should go a million rounds or so ...
