Well I realize that not all will come out the same, but I meant the entire process itself of cold bluing kit by birchwood
Well I don’t think length matter when it comes to being a non fireable wall piece
My old Winchester is a 69a from 1954-1957
It sure the hell does. You can cut to a min. of 18" , but I would cut at 20 inch .
If the bore is good , then this is worth redoing , IF you want a project,
But if you are new at this and thinking to buy it and fix to make some money, don't bother.
I like stuff like this and have the tools to do it, been at it for 60+ yrs.
You can uses anything for lub when sanding , light oil, WD 40, water, as long as you wipe it dry after.
When you blue, has to be clean and no oil or finger prints on the steel
Brake clean makes a good degreaser.
I have used a bead blaster( sand blaster with glass beads) for this type of thing, works good.
But if bore is rust , pitted, walk away unless you want parts , or just hang on the wall.
remember if working or a rusted glob of rust, legally it's still a gun, unless you weld the barrel to the receiver.
