The biggest problem for cleaning those In#@@#$ guns is the plastic fouling you get in the barrel from the sabots used, or the lead fouling in the barrel you get if you use a lead conical. Both require solvents to remove the lead or plastic, beyond removing the salts from the substitute powders. The salts will come out with soap and water. The plastic and lead need work with a bore brush, and a proper solvent for whatever is there. You can't leave the plastic or lead build up, because it may be covering some of the salts of the powder, and those salts will begin to corrode the bore under the plastic or lead, or both! So, you end up scrubbing with that bore brush, then soaking the barrel in solvents, waiting for 15-30 minutes to give the solvents time to work, then back to scrubbing the bore again to get the lead and plastic out. Then you use alcohol to neutralize and remove the chemicals from the solvents, then soap and water to remove the last of the salts, then oil or lube the barrel for temporary or long term storage, respectively. Those new wonder guns don't save you any time cleaning, but rather require extensive efforts to get them as clean as a tradtional ML rifle shooting BP, and a PRB. The cloth patch keeps the lead from touching the lands or grooves. Black powder is easily (and easier to) clean with soap and water. Rinse with water. Dry with patches, then oil or lube for storage.
The only time I have had to use a bore brush to clean my traditional rifle was when I burned through a powder horn ,and half of another horn of powder shooting blanks at a parade. I had so much crud in the barrel that I used a bore brush to break it off, then cleaned with soap and water as I would normally do.
We may not like your choice of gun, but since you spent the money, please take care of it properly. If you don't shoot the gun for several weeks, or month, slosh some alcohol in the barrel before taking it out again to shoot or hunt to dissolve the lube or oil that you put in the barrel for storage. Based on tests done here, I think I would have to recommend you buy a can of ballistoil and used that to lube the barrel for storage. It seems to resist corrosion the best of all the oils and lubes tried so far.
If the gun is stored stanind upright, on its butt, oil will slowly fall to the breech of the gun, and will congeal in the flash channel leading to your nipple. So, in addition to sloshing alcohol in the barrel to clean it, and running a couple of patches to pull it all out, use a pipe cleaner to clean out that flash channel of grease and oil. Fire a couple of caps off, in your garage or back yard, to make sure the passage is clean and dry. Only then will you be ready to load the gun again and go shooting.
I had a very good friend who won one of the modern wonderguns in a Pheasants Forever Banquet raffle, so he set it up for his son to use deer hunting. The first year, the son shot two deer off the back porch with it. He was in college, so he did not get back home to practice with the gun again before the next season. The gun spent the year standing upright in my friend's gun safe, with oil in the barrel. The kid drove in the night before deer season opened, got up the next morning, dropped a powder load down the barrel then a sabot and bullet, and then primed the gun with a shotgun primer. A nice buck came out of the woods towards the back yard just after dawn, and the kid squeezed off a shot. The primer fired, the main charge didn't. He primed again, and fired, but the main charge didn't go. The deer finally wandered off, probably not aware of the kid's presence.
Junior woke Dad up to help him pull the load, and they cleaned the gun. Dad called me the next day, and asked me what I thought had caused the misfire. You all know that answer now. Junior killed another deer the next day, with the gun. Dad and junior learned that the new wonderguns can't just be left in the case all year long, like some people do with cartridge guns.
