Shotgun Cleaning

(Courtesy of Otis Technology, Inc. Please check out their large supply of gun cleaning products.)

Basic Principles

The bore of a shotgun should look smoother and more polished the more you shoot and clean it. If you notice lead or plastic in the barrel you will also see scratches. The scratches are caused by going back and forth with the cleaning implements. The abrasive dirt in the muzzle was brought back into the chamber and forcing cone. Conventional cleaning equiptment will not clean the forcing cone. This dirt is fired down the barrel and the scratches result. The scratches allow the lead and plastic to adhere to the bore. If you clean the chamber and forcing cone and only go in the direction of the projectile, the bore will not be scratched. It is no longer necessary to disassemble a shotgun for cleaning. Just open the action as you would to insert a shell. Run the flexible steel rod down the barrel and pull the Otis patch out the bore. It now takes only a minute to correctly clean a shotgun.

Shotgun Cleaning

1. Put the tip in slot B, the largest hole.
2. Place a patch saver on the tip and over the patch. The large patch saver is for 12--10 gauge, small for 20--16 gauge. A patch saver forms a large knot that varies in size as it is pulled down the bore.
3. Take a pinch on the patch and place it through the slot.
4. Pull tightly. This lock the patch and patch saver onto the brass tip. It is impossible for the patch to come off until you release it. Normally with a slotted tip, you randomly clean each side of the barrel. With the Otis system, you clean the entire surface of the barrel.
5. Assemble the flexible cleaning rod. Obstruction remover on one end, forged brass tip on the other.

NOTE: The shotgun tip has a new internal thread for strength.

6. Open the action as if you are going to insert a shell.
7. Push the flexible cleaning rod down the barrel from breech to muzzle. The obstruction remover on the end of the rod will knock out any mud or snow in the barrel. You can remove stuck cases or sometimes a stuck wad.
8. Work the swab in the receiver to clean the slides. Pull the rod and swab out through the muzzle in the direction of the shot. The swab will scrub 360 degree coverage the entire chamber, forcing cone, length of the bore, and the choke are cleaned in one stiff pull.

If the swab pulls hard, just attach the "T" handle and pull. Your first swab down the barrel must have a few drops of solvent on it. This will lubricate the bore and prevent sand or dirt from scratching the muzzle end of the barrel

9. After the first swab, you can use the brush. Please note that the Otis brush is oversized to scrub the chamber and forcing cone.

Never run the bore brush down the barrel of any gun first. This will damage the firearm. The dirt or sand in the muzzle end will get into the bristles on the brush. When the brush is presented at the forcing cone, the dirt will be deposited in the chamber. This is the exact equivalent of cleaning in the wrong direction (from muzzle to breech).

The Otis all-caliber swab has six new cleaning surfaces. Take advantage of this feature. It will prolong the life of your firearm. When the swab is pulled down the barrel the first time it may pick up dirt or abrasive particles.

Never run this swab a second time. The abrasive material will scratch the forcing cone and bore at the breech end. This causes lead and plastic buildup.

10. Remove the swab and flip it over. Use the clean side of the swab.
11. Use the chamber cleaning rod with the oversized bore brush to clean the chamber and the choke tube threads. It is always desirable to clean the barrel first before changing the choke tube. This will prevent dirt from getting into the threads. If you find the choke tube does not easily screw in, do not force it. A bulged barrel could result. Clean the thread right there and reinsert the tube. Many hunters have saved their hunts by having the Kit and Caboodle with them on their belt.
12. It is always a good practice to wipe down all of the components when you put them back into the dust-proof case.
