Yes, I'd be pleased to do that. Several years ago I discovered that many shooters were not really cleaning their shotgun barrels. They might run a bore snake down the barrel or maybe brush it but that was about it.
At best that procedure only removes some of the plastic from the wads and some of the carbon residue. Mainly, it spreads it around so that the barrel may look clean but in reality it's still very dirty.
You can read about the procedure I refer to as "deep cleaning" at http://www.allaboutshooting.com
under "Cleaning a Shotgun Barrel" but here are the basics.
You'll need a space where you can work and that's at least 70 degrees, some rags, newspaper, cleaner or solvent like Hoppe's #9 or Gunzilla, a new or excellent condition brass/bronze bore brush, a cleaning rod, an old bore brush or a tynex bore brush, some patches and a minimun of 20 - 30 minutes.
Remove the barrel from your gun and put a flush mounted choke tube in the barrel, improved cylinder is best because it's easier on your brush. Spray a good bit of cleaner into your barrel and on your brush. Scrub the barrel with the wet brush and periodically spray more on the brush and into the barrel. It's a messy process.
Literally, scrub it for 4-5 minutes. The bore should be wet during this entire process. Now, with the bore still wet (spray more cleaner if necessary) go away for at least 10 minutes and let it set wet.
Now for the finaly process, spray more cleaner into the barrel and on your brush. Scrub it again for a few minutes.
Here's where I switch to an old bore brush or preferably a tynex brush. I put a good cotton patch over the brush and swab out the barrel until it shnes and a patch comes out really clean.
Remove the flush mounted choke and clean the interior threaded portion of the muzzle.
I use the same procedure on the choke but I use a brush made for that purpose or an old bore brush. Turkey chokes are very hard on bore brushes.
I know this procedure sounds very simple and it is but it just works. Many folks have used this procedure and saved themselves a good bit of money by not buying another turkey choke. Sometimes just cleaning a barrel and choke will really improve the performance.
