HW/Weihrauch HW97k barrel cleaning

Thats plenty. Hoppes is plenty aggressive, just keep it clear of the seal! Id follow up with ballistol or just use ballistol regularly and hoppes on occasion for deep cleaning.
Patch or felt plug is plenty, yes you can go more aggressive but not necessary. Your just trying to pull out the excess lead buildup is all.
 
I use a Patchworm cleaning kit, and I found I had to use 2 patches to get enough compression to remove lead in my HW97. It's difficult to pull through, but it does work.
Yep, maybe not enough patch to offer any resistance. I use 2" pro shot patches pulled thru with a Otis pull thru. If it's really dirty The first two patches will have lead particles or flakes on them. I mainly use ballistol, but have used Hoppes #9 and alcohol. I usually pull 5 to 7 patches before I'm satisfied it's clean.
 
On my HW97k .22 I use the .223 cal flannel patches and no plastic insert on the patchworm. It's the perfect compression on the patch.

I do the .177 barrel with the same patches tied in a loop with a piece of cotton twine. I'll put 2-3 patches in a line and a couple drops of kroil on the first one.

You don't have to worry about the breach seal on the HW97. Most solvents won't hurt it and it's in the compression tube anyway. When the loading port is open its retracted far behind the breech. You can slop solvent anywhere you want and it won't get near the seal. Don't let it pool in the loading port and you are good to go.

Springers and pellets don't "lead up". It's just a few particles that get cut by the rifling. A drop of penetrant and a couple patches is all you will ever need. I like to pull a patch damp with acetone through the bore after I'm done to get all the oil out. But that's probably overkill. It sure gets the bore squeaky clean and dry and I have always believed an oil free bore shot better.

I'm a thrifty SOB and I use both sides of the patches. I'll reverse them on the patchworm so the fresh side is wiping the bore. So I'll use 3 patches to clean and one damp with acetone. I usually leave that acetone patch on the string and use it with kroil for the first patch next time. So it takes 7 passes and 3 patches to get the bore as fresh as a spring flower.

The parting compound on Crosman pellets is black Graphite or something. It's nasty to get out but I don't think it hurts a thing. New barrels have waxy cosmolene that simply won't come out without cutting it with acetone. And a dieseling gun puts burned grease film in your bore. The acetone is dandy for all of it. If a couple solvent patches don't get it all then try the acetone patch a couple passes. The next patch will be white as snow.

Now, when working on my 97K, I've got this really cool safety device that I put in the breach, I can't remember who makes that thing???, but it's beautiful and looks as nice as any of my rifles stocks, ✋👀 👍 well what would acetone do to such a device as that, if I were to drip some on there?

I shoot only JSB or AA pellets in my hw97k. Mostly the 10.3s, but occasionally also the 8.4s. Just to stake out the other end of the spectrum, I never clean my barrel. After tens of thousands of shots, accuracy remains great.

Yes sir I've only cleaned my barrel on my .20 cal a handful of times through the years! And only if accuracy drops off.
Nothing corrosive in airgun shooting so it's not imperative to keep it squeaky clean! Infact it usually takes several shots to get accuracy back after a good cleaning!

It would dry it out and strip the wax/oil.

I just use a damp patch so it does not pull off a drop when the patch compresses. It just brushes by the wood. But after some solvent hits that wood its bound to strip it. No worries. It's just a chunk of wood. Oil it up and shoe polish it of it gets dry.

Acacia grows fast but it's super dense. It's hard. They used to use it for nails in drilled holes. It won't absorb acetone or much oil. So it's just the surface finish that's wiped off.


I'm not sure about acetone, but if you get acacia shavings in a shot glass of tequila, it turns it cranberry red.
