I got my brass rods from the machine shop, one for .32 and one for .38 calibers. They cost me $20 for the pair of them.
I worked on hammering the stuck bullet out of my Nagant revolver, and it would not come out, althought it moved a little.
So I poured some CLP Break Free down the barrel from the chamber end with the gun pointing muzzle down, and left it there for a week. The liquid did not run out, but stayed at the same level the whole time.
Today I drained the oil and tried whacking the rod again (from the muzzle end). At first, nothing. Then I finally got the bullet out. Took about four or five whacks with a plastic hammer.
Inspected the barrel, and there is no damage or sign of anything unusual -- just a shiney bore (after running a bore snake through it.
So, those two rods were a good investment. A gunsmith would have charged at least $20 just to remove one bullet from one gun. Now I have a rod for each of my two calibers. I'm glad I didn't get wood ones, as the brass seems to be the perfect material.
Next time I have the problem, I'll use the rod and hammer right way, before the lead has a chance to cool. It should come out much more easily.
Thank you all for your help!
