A barrel I want to salvage
« on: June 05, 2023, 12:38:14 AM »




Here a couple of pics of a barrel I would like to use. It has seven grooves so I cannot accurately measure land to land. The best I can do is 3/8" with my calipers. The barrel is currently in a half-stock but  lugs have been removed that indicate either  the stock has been shortened or changed. How should I start, knowing the barrel is unloaded, and unobstructed, to clean the bore? And what caliber would it be? 40? Thanks.

If you know someone with gauge pins, you could have them help you determine what the bore size is.

I start by un-breeching the barrel. If it has a drum, often it is threaded into the breech plug and it must be removed first. Next, I start with a loose-fitting jag- green scotchbrite combination with the barrel saturated with any water-soluble solvent like WD-40. Expect to ruin a lot of scotchbrite. Sometimes Iíll plug the barrel and drum and fill it with solvent to loosen things up. After I get to where I can pass a scotchbrite patch without shredding it and things are not muddy I take a look. Then decisions are made on whether I will re-cut the rifling.

The muzzle looks filed or coned. You will need to push a lead slug through the barrel and measure that to get an accurate bore diameter. The muzzle is larger than the bore.
As in life; itís the journey, not the destination. How you get there matters most.

The breech plug came out easier than I expected. I pushed several pieces of red scotchbrite pad thru the bore and it now looks pretty good. The barrel will soak for a few days in Evaporust.

I am pleased at how good the barrel looked after about 14 hours in Evaporust. I believe it will brown nicely when the time comes.  There are very few dents and dings to fix.
 I found a drill bit that fit the bore, a little on the tight side, and checked it with my micrometer. Looks like .3518 +/- to me. I suppose I'll try .350 balls and figure out what patch to use?
It's all back in the soak ' til tomorrow. Then I'll work on cleaning the bore some more.

The bore is not cleaning up like I hoped it would. My original goal was to at least get the lands shiny. Now I would settle for a bore that did not snag patches. I'm still working on that.

Send it to Rich to fresh up the rifling for you!

There is a fascinating section in the book "For Beginners Only", which goes into detail about salvaging old bores.
