...it may be a rusted bore that is fouled up..?
Ar any rate use a new bronze brush on a good rod. Wet the brush heavily with Hoppes #9 and insert it from the chamber pushing it all the way out the muzzle. Wet the brush and pulkl it back through the barrel. Wet it again and now stroke it though the barrel in both directions, always exiting the barrel at each end, several times. Now dry patch the barrel and inspect it. When you first start doing this, if the bore is rusty, it should be evident on the rusty wet brush as it exits.

Ceska said:Your joking right?
Try the foul out, or another heavy duty cleaner for the lead, Hoppes won't cut it. Spray your barrel down and let it sit over night.
Never run a brush back and forth in the barrel. Pull it from chamber to muzzle, remove and repeat.
Just my 2 cents.
