Check to make sure the rifle is unloaded and the magazine is empty.
The most important rule of gun cleaning is to always clean from breech to muzzle in the direction of the bullet. There are no exceptions to this rule. If you go in the wrong direction ("muzzle to breech") you will bring powder residue and abrasive dirt from the barrel into the chamber and neck. This causes stuck cases and other malfunctions of the action. The next bullet down the barrel will drag this dirt and erode the bore.
Overview
- Pull a patch with solvent through the bore to mop out any loose residue and dirt.
- Pull a brush. Turn it to clean the neck and shoulder of the neck.
- Pull a new swab to mop the residue the brush loosened.
Otis All-Caliber Swab
The All-Caliber swab will clean from 22 to 45 caliber rifles. The swab is a significant break through in gun cleaning. This one swab replaces five different size patches. Each swab can be used 6 times offering 6 new clean surfaces
- Slot "A" is used with the smallest brass #2 tip. This cleans 22 to 30 caliber
- Slot "B" is used with the middle size #3 tip to clean 30 to 45 caliber. Refer to Chart B for detailed pinch locations.
|
1. |
Take a pinch on the swab. Pinch the swab upward as illustrated. |
|
2. |
Feed the tip of the fold through the slot in the brass tip. |
|
3. |
Pull the fold through tightly to lock the swab on the tip.
This will make a knot that will scrub deep into the rifling.
- You have now created a cone that will give 360 degree coverage.
- By pinching in different locations you can vary the size of the swab.
|
|
4. |
Apply 3 to 5 drops of solvent to the front end of the knot in the swab.
- Do not dip the swab or brush into solvent. This will allow excess solvent to wash residue into the trigger group.
- The solvent will be squeezed out of the swab when it enters the shoulder of the chamber. The solvent will flush ahead of the swab knot and lubricate any abrasive dirt in the bore.
- It is not necessary to disassemble the rifle. Just open the action as if you were inserting a cartridge.
|
|
5. |
Run the cleaning rod down the bore in the natural direction of the bullet.
If the rifle has limited breech access (22 rim-fire semi automatics etc.), place the
tip with swab into the chamber as you would insert a shell. Run the rod into the
barrel and turn to attach the tip. Pull the residue and dirt from the barrel in
the direction of the bullet. |
|
6. |
Turn the rod as you enter the locking lugs.
This is the most important area of the rifle.
- Use your finger to force the turning swab into the recess in front of the lugs.
- Continue turning the swab as it enter the chamber. This will mop out the gummy buildup at the shoulder.
- Continue to turn the swab as you enter the neck to clean and lubricate this area.
Now that you have cleaned the loose residue out of the receiver, locking lugs,
chamber, shoulder, and neck, we will clean the bore. Do not worry about swivels,
for the rod rotates within itself. Use the "T" handle if you desire. Pull
the rod and swab in the direction of the bullet. |
|
7. |
Turn the swab over and use a new surface for your next cleaning cycle. |
Using Chamber and Bore Brushes
| 1. |
Attach the brush to the end of the flexible rod. |
| 2. |
Turn the brush to first loosen the residue in the neck. |
| 3. |
After scrubbing the neck pull the brush in the direction of the bullet "breech
to muzzle" |
| 4. |
Now run the swab as we described earlier. This will mop out residue you have
loosened with the brush. |
| NOTE: The neck is critical to the accuracy of the rifle. When the new round is inserted the brass case is a few thousands of an inch from the throat or start of the bore. The new bullet rests at the start of the throat. When the rifle is fired the case elongates to the shoulder of the neck. If dirt is present the bullet gets trapped and has a later release time. The bore brush is made oversize to scrub this critical area. |
Obstructions
If the chamber is not maintained properly fired cases may get stuck in the chamber. This will also occur in cold weather situations.
To remove the case, run the flexible cleaning rod into the bore, and with rapid taps hit the base of the case. Eventually, the stuck case will be removed.
