rust pitting

[Mr Hawken]

i have found small rust pitting in the barrel of my t/c renegade.i have always used the water method and oil right after.i owne a hawken for 10 yrs and never had a problem could this be a poor blueing job? any ideas how to get it out? will it shoot out? its not very deep.

you might try making a patch out of a peice of 3M handpad, fine grit and scrub the bore. it sure will shine the bore up, I don't know about pitting.

could this be a poor blueing job

is the rust inside or outside the bore? They don't blue the inside of the bore.

 

[Mr Hawken]

my mistake i thought it was all blued. the rust is on the inside. what about fine steel wool.i have not noticed any change in groups what about shooting it out?

When you use the word " Pitting " I tend to think of potholes in the street that will break an axle, or tailpipe if you aren't careful. Shallow pitting can be taken out with lapping compounds, even toothpaste, or JB Bore Cleaner. The Green Scrubber can also be used. Steel wool will knock off surface rust, but generally is too soft to do much about pits.

There is a technique referred to as "fire-lapping ", where you coat the patch you use around a round ball with lapping compound, and fire the gun off, repeating this process, until you have removed the rust or shallow pits.

For deep pits, there is nothing that can be done save re-boring the barrel to a larger caliber, if that is even possible. Sometimes its cheaper to get a new barrel! I would not go to that expense unless the exising barrel absolutely will not shoot at all.

I have an old German Mauser I bought from a large discount store. They had shot corrosive primers in the gun, and it had not been cleaned. Both the lands and grooves were pitted. I jsue JB BC on it repeatedly and finally got the lands shiny and polished. But the grooves remind me of pictures of the Burhma Road! The barrel still shoots metal jacketed ammo okay, so unless I decide to change barrels to a new caliber, I will probably keep this as is.

Since it is fine rust spots on the outside of your barrel, I'd use fine steel wool and oil. Just rub it lightly and it should remove the rust.

I had an old M1 Garand rifle once that shot better with the original pitted ordnance barrel than with the Douglas barrel that replaced it. Go figure. The proof is in the pudding. If the rifle shoots okay, I wouldn't worry too much about a few small rust pits.

I would scrape at the pits with a sharp piece of wood coated with a bit of oil. Then I would look for brass wool rather than steel which would be my last choice.
