Yes as far as the description of the pits, they are so tiny they look like pin pricks. No true holes. Come to think of it, they did become more noticeable after I gave them my end of season wire brush-out with Hoppe's #9. There very well could have been there all along with some oil obscuring them. I am pretty confident the gun has not been shot 300 times since its 1974 reproof.
I am cleaning them as I would steel barrels. Are there any special cleaning measures or precautions I should employ for Damascus?
