This is just unbelievable. I'm cleaning my Marauder 177 because it started hosing the pellets. I knew it was time for a cleaning. I started by pushing a couple of wet (balistol) patches through. Then a few dry ones and they still came out black. So I realized the barrel must be really dirty. So I got my nylon brush, dipped it in balistol and scrubbed back and for for about a minute. A few patches through and I thought it should come clean like always.
But I was wrong. Still black patches. I repeated the above process 4 times and still get black patches. Normal cleaning is maybe 25 patches. I pushed 2 entire packages of 100 patches through this gun and they are still coming out dirty. I can't believe it.
Now I'm out of patches and it still isn't clean.. Maybe I should hook it up to the garden hose.......

Do you use crosman or H&N pellets the most in that gun? The antimony in their lead bonds with the steel in the barrel and is a pain to get out, always leaving your patch gray. If not maybe clean the barrel after a quarter of the shots that you put through before cleaning this time. That way it's only 1-3 patches every 250rds or so.

I was checking back on the last time I cleaned this gun. I had about 5 tins or 2500 shots through it and it was still shooting just fine. When I cleaned it then, I faked myself out by just pushing a few patches through and the last one came out only slightly grey. I thought it was fairly clean. But then I wasn't using any solvent at the time. Now I have put probably another 10 tins or 5000 shots through it. So it was excessively filthy. I take the blame for not cleaning it better the first time. 

But my point was, I've never had any of my guns get this dirty and be so hard to clean. I've been shooting mostly JSB 10 gr in it. 
I think I just went WAY too long between cleanings. I really thought that a good minute or two with the nylon brush and balistol would loosen up just about anything and let me clean it out with patches. Evidently I was wrong.

I cleaned this gun when I first got it and it was clear white patches after about 10. It took about 20 shots to get is seasoned and it started shooting really great. Even though I don't think the gun is totally clean this time, I did put the gun back together anyway and it when right back to nailing hole in hole. So What else can I do that will get the barrel really clean so that I have a baseline to start with again?

Why not use a true lead removing solvent like Hoppe's No. 9 or CLP? get the heavy fouling out, and then finish with Ballistol. 

Yes, I too have heard from other forum members that Crosman and H&N use alloy to make their pellets, and that this leaves a good deal of fouling in the barrel. I have also heard that lubricating alloy pellets can help with this issue and reduce the fouling, and thus the cleaning interval of your barrel. 

Good luck.

So my condensed version for getting your barrel back to bare metal:

-Remove the barrel
-Plug the muzzle tight.
-Fill with solvent of choice.
-Let it sit for a few hours to overnight.
-Drain the barrel
-Run your nylon brush with more solvent on it through the barrel many times.
-Run a patch or three through every 20 or so passes with the brush to check how clean it is.
-Once happy with the brushing get all the gunk out and make sure a patch put in dry comes out dry(even if still a bit dirty).
-Using JB Non-Embedding bore paste(grey in color) embedded in a .177 bore mop pass that through from the breech to the muzzle but not back the other way 10 times.
-Clean out with a bit more solvent and patches. If your patches are still coming out dirty use the JB and mop for 5 passes and recheck.
-Once satisfied it is clean(inside of barrel should shine with no apparent bump humps or defects) run an oiled, then dry patch through to protect the barrel before shooting again.

I will warn the overdoing it with the JB can ruin your barrel so take your time and check every 5 passes after the first 10.

Bill,

I have a Benjamin Marauder, gen 1, that I have used pretty much exclusively for the last year and a half or so in Field Target WFTF competition. It became very erratic in its performance, so I decided that it had to be cleaned. Removed the barrel, scrubbed it with good 'ol Hoppes #9, until the patches were clean. I then used Corbins benchrest bore cleaner, and was aghast. They came out pitch black. Took another 100 + patches to get them to come out clean. Thought Hoppes would have done it, but not the case. Since then, I have lubed my pellets, and this has not happened since.

I use nylon or phosphor-bronze bore brushes. I also clean them after every session. I let them all go for up to 75 rounds once, listening finally to those that say only clean it when accuracy falls off. Chrono test showed losses of up to 100FPS. I run 2-3 Rem-Oil wetted patches through, then a bore brush soaked in it. Then more Rem-Oil soaked patches until they start looking pretty clean. Then dry patch a couple times till dry and clean. Usually no more that 6 to 10 patches.

"fpgt72"I always had to take the shroud off, or at least all the baffles out as it would hang up on the spring and all that junk at the end....they do get nasty also.

My gun likes H&N and is always grungy, I just toss the baffles in a sonic cleaner (no heat) they are usually black in no time.

Yes I pulled the barrel and removed the shroud. I did notice some junk in the air stripper at first, but it was clean after maybe the 15th patch. Still haven't pulled this gun apart again and cleaned it. AND, it used to be a tack driver and it has lost its way again since the cleaning. I'm starting to wonder what happened might have been something other than just being dirty. ???
If I find anything when I clean it next, I'll post again just FYI.

Thanks for all the input folks.

Will add: BE CAREFUL with the JB bore paste (Especially if it’s a traditionally land and groove rifled barrel!), and make sure it’s not the JB Bore brite!, both can & will lap your barrel, bore brite is coarser I belive?, if it’s lead?,remove it with shooters choice lead remover, good stuff!, not sure I would let any bore cleaner set in my barrel overnight? (unless it’s a SS barrel!)
