A guy brought me an old pump action FN (Belgium made) 22 so I could clean it for him but when I tried push my cleaning rod in the end of the barrel it would only go in an inch..!! so I took a small #10 drill bit ,put it in the barrel and turned it by hand, I managed to get some of the junk out and it looks like carbon and lead. But I can only go so far with the bit and still can't get the rod in more than 3-4". Any ideas how the get all the junk out???
Also I'm trying to find the model , all that maked is Fabrique National d'Arme de Guerre Herstal Belgique and 22 L plus proof marks SN 34### It looks some what like a Winchester 61 and it's a take down
Thanks

Well for one thing Don't use drill bits to clean a barrel . Use a .177 (17 hmr) cleaning brush to start . then go to a 22 brush . Then get some cleaning cloth made for lead removal . ( can't remember the name of it ,I have some & it works good) keep at it till its clean . Gun is probably a "Trombone "
 
It is a Browning "Trombone" and should be inspected and cleaned and tested by a gunsmith.

All of my # 10 drills are the same size, there are no large or small ones... :D
 
Thanks for the replies, at least we know what it is:) I'm going to have to find a 17 cal brush, all I have is a nylon 17 brush. As far as using the #10 drill bit ( notice I didn'y say small:)) it was just to try and see what was in the barrel and I turned it by hand ..very slowly. At least now I can see throught it and looks like a sewer pipe. Does anyone have an idea what could have caused this built up of lead and carbon at the muzzle??? The fact that it is marked 22L would that mean it was meant for only Long and Short cartridges ??

The build up at the muzzle isn't anything I have seen or could guess at...

If the bore is toast and everything else is working fine it can be lined and shoot as good as new. (Usually $175)

It was originally for shorts and longs but the only difference up to the long rifle is the bullet not the brass. They handle LR's fine.
 
I have one as well.watch the fore end screws coming loose through use as they fall out easily.A tappered affair and the slot too small for most screwdrivers.Fun guns .....................Harold *Do you have the round tang or square one?
 
I had a mossberg like this it was completely packed with lead only a pin hole of light through it
As i recall it took me forever to get it cleaned out
It was actually coming out in chunks!
 
Camk, do you have any idea what would cause this type of blockage, I mean between the last time it was shot and this type of condition..something must of happened:confused: Anyway it's a ##### to get this thing clean:mad:

Thinking about this all I can come up with is an extremely rough and pitted bore, so rough and pitted it filled up with lead and built up to the stage it is at now. I don't see it as carbon build up...
 
Well now I'm up the famous creek without a paddle,:redface: yesterday after soaking the barrel again in Hoppe's Benchrest solvent and brushing with a 17 cal brush,was able to get a lot of junk out...when I started to use an old 22 brush and while pulling in out towards the muzzle ...the brush broke off the rod:eek:Now I've got a brush stuck about 6 inches from the muzzle. Can some one help me here, how do I get the breach block out of the action so I can get access from both ends
Thanks
Bob
 
I'm doing this from memory, since I sold my Trombone....
The rifle takes down with a big screw on the side of the receiver. Then you need to slide out the small block at the bottom front of the receiver. It slides to the rear. It is held in by a 2" or so "arm" that has a notch that hooks in place near the fore end. Lift the arm and slide the block back. Then you should be able to remove the breech block when you pull the fore end back. The ejector will still be in your way if I remember correctly. Good luck!
