Hello fellas. About 6 or 7 months ago took my SVT40 out and ran maybe 50 rounds through her. Just a magnificent piece to shoot. Afterwards, brought her home and cleaned her using Hoppe's #9, as it is purported to be suitable for cleaning after corrosive ammo.
Ran a patch of Breakfree CLP down the bore as a preservative, and put her away in the safe.
Took it out the other day to examine, and looked down the bore and it did look a bit fuzzy. Ran a dry patch down the bore and it was very sticky black stuff. So attacked it again this time using TM solvent and several brush strokes, and removed a whole bunch of thick black sticky stuff. Fortunately, no rust was evident on the patches.
I find myself trying to figure out what that stuff is, and suspect perhaps the old Czech ammo used asphalt or tar sealant, and perhaps that is what I was struggling against.
Bore is nice and bright and clean again, but my that was unpleasant stuff to remove.
Any ideas what it could have been? Didn't feel like carbon fouling, as it was sticky. If it is asphalt or tar, I reckon a little Sunoco race fuel might cut through it a little faster next time. Maybe CLP might cut it faster, as it is oil based.
