While cleaning the barrel of my Taurus PT-92 last night I saw what appreared to be barrel erosion just past the chamber. The wierd thing is that it is only on the left side, between about 7 and 11. It looks like the erosion you see on old corrosive ammo bolt guns. I bought the gun used but the barrel was pristine. I have shot no more than 5,000 rounds through it, mostly lead reloads and WWB bulk stuff. The accuracy does not seem to have dropped any. I find it very odd that it is only on the left. Anyone have any ideas?????..... :confused: :confused: :confused: :confused:

It could be rust which just looks like corrosion. Or it could be some stubborn burn residue refusing to get out...... if the latter, get some J+B bore paste and a nylon brush and scrub until your elbow gets tired.

Lead buildup is the other possibility. You say you shot a lot of lead down it. I was cleaning a Megastar .45 once and thought I had somehow removed 2/3 of the rifling. Then I realized that was unlikely as hell. Scrubbed and scrubbed and it started flaking off. Took a lot of work, but I got it back. And then used jacketed as much as possible thru that gun.

It sure looked /exactly/ like the barrel steel, though. There are lead solvents, I think, but I'd just go outside, with a throwaway shirt on and get a big bottle of hoppes or equivalent and a bronze brush and scrub it like hell.

If you shoot a lot of FMJ it is likely lead buildup. Clean it with some JB Bore Paste.

The easy way to remove severe lead fouling:

Method 1;

Get some Kroil; a low viscosity, low volatility, high efficiency penetrating oil. If your local gun store doesn't have it you can get it from Brownell's.

Get a Chore Girl copper scouring pad, available at better grocery stores everywhere. Cut the rivet out of the middle and unfold it. Cut it into squares about the length of your bore brush, and just wide enough so that it won't bind too severely in the bore when you wrap it around the bore brush.

Soak the bore, dripping wet, with Kroil, let it sit for at least an hour, maybe overnight, and soak.

Scrub the bore with the scouring pad wrapped around the bore brush.

Watch the lead come out in sheets.


Method 2; less elbow grease, more expensive;

Get an Outers Foul Out with the lead solvent and follow the instructions.

I don't try to push lead bullets fast anymore, but when I did, the Lewis Lead Remover worked well. The Python and SAA New Frontier accumulated lead build-up more than the Smiths.

The Lewis Lead remover is in the Brownell's Cataloge.
