In my continuing struggle to present worthwhile subjects, I will teach you fellows how to clean a shotgun.
First, make sure that it is empty.

Then remove the barrel.

Put the rest of the shotgun away.

Spray WD-40 down the barrel.

Do it from both ends.

Scrub the barrel with a bore brush, if necessary.

Select one (1) Tampax.
Original, Regular is just right for a 12 Gauge.

Remove the Tampax from the convenient holder.

"Fluff" it up some and spread it out.

Use your cleaning rod to push it through the bore.

It will exit the barrel dirty.

Turn it around and, after re-spraying the bore with WD-40, run it through again.

Hold the barrel up to a light to see the fine job you did.

There you have it boys. You've learned something important today.
Conclusion:
Tampax aren't just for ladies.
