Help barrel leaded

[byf43]

Got to the hardware store, or PepBoys, and get some Kano Kroil or Aero Kroil (aerosol) and spray that inside the barrel.

This is called "the oil that creeps'. It will get behind the lead and help you brush it out.

If we were closer, I'd give you some to use.

If you want to determine if a chore boy is steel or copper, use a magnet.

If I don't get the last of it out tonight, I'll get some kroil from Home Depot before work.

Other things to look for are too hard a bullet for the speed you are shooting, an under sized bullet or too tight a chamber.

Huh???

I have never heard of leading from too hard of a bullet. Too SOFT, yes, that is a common cause.

How does too tight a chamber cause leading?

If he is referring to the cylinder throats being too tight - the bullets get swaged in the throat, and tilt in the bore which can cause leading. This is on a wheel gun though.

I was referring to the chamber mouth on a revolver. When the mouth is too tight, it swages the bullet down. Now you have an undersized bullet entering the forcing cone which leads to gas cutting of the base of the bullet. Ruger was notorious for this but some Smith's have also had issues.

Lead bullets that are too hard FOR THE LOAD will not obdurate properly in the barrel again resulting in gas cutting. For lead loads 800 and below, you can use soft lead as long as you are .002 over groove diameter and have a good lubricant.

 

[Pinecone]

If your bullets are sized right, they will not need to obdurate. I have always shot HARD cast bullets. When I cast my own, it is from straight Linotype. And I shoot mainly .45, so not high velocity loads. And I have shot many thousands of lead bullets with no leading issues.

I can see the chamber throat issue in revolvers.

True, but if I ruin the barrel , then I won't have a 44 anymore and probably won't get it fixed or a replacement for some time. In reality I would have to sell my hi power to get it running. I would rather not be out of a gun if possible.

I use Kroil and a copper choreboy on the Les Baer after every range session.

Let the Kroil soak for an hour before hand.

No kroil at my Home Depot. Just checked.

Do you have a PepBoys auto store, nearby??????


I don't know if AutoZone carries it, or not.

Possibly NAPA carries either Kano Kroil or Aero Kroil.


I've got 3 cans of the stuff sitting on the shelf, in my workshop. (I know that won't help you right now, though.)

Yeah there is a pep boys, I just work walking distance from Home Depot so figured I would check there on the way to work.

Swing by the grocery store and get a copper pot scrubber and use pieces of it wrapped around a cleaning brush. It will push out the lead. Harm free.

Just make sure it's actually copper and not just copper plated.

Color me crazy, but gun barrels are hardened steel right? And also consider that common bullets are copper jacketed, so any kind of copper or bronze wool would do a good job of scrubbing out the MUCH softer lead while not damaging the barrel. Isn't using a solvent soaked bit of bronze wool on a jag a common practice for removing leading?

 

[sxs]

I don't cast my own bullets...but I have made liberal use of hard-cast that I have purchased from others. Swaged bullets can and will lead your barrel if you push them at any decent velocities. Even hard cast I keep moderate to light loads. For full bore magnums, I always use jacketed bullets. Best hard cast I've ever bought (.357 and .429) were some that were hard cast, sized and lubed nicely as well as stored nicely in hand made frames from a guy who used to sell them at the old Jefferson (Maryland) gun show out between Harper's Ferry and Frederick, Maryland. Man, I wish I knew how to get in touch with that guy! I had worked some really good target loads from those bullets!

Hey, Pinecone, I thought pure linotype was somewhat too hard. My friends who cast, IIRC, were using 1/2 to 1/3 linotype to wheel weights or other soft lead.

+1 on the Lewis Lead remover. Worked well the one time I used it.

 

[sxs]

That's true as long as they are copper. I have found Copper Colored scrubbers that look the same but they are strands of copper colored steel. Now I take a magnet with me to check if they are the real thing.

OP, leading in the first couple of inches is usually from undersized bullets or from too mild a pressure for the hardness of the bullets. I don't think you have tight chambers as you haven't encountered this problem before.

I missed John's comment before posting the the same opinion myself. I think (my supposition...never heard or read this anywhere) sometimes copper wash is used over steel to reduce rusting with steel scrubbies.

No kroil at my Home Depot. Just checked.

That's alright - just use your Hoppes No.9 and scrub a bit more.

+1 on chore boy. Kroil is nice but not a necessity.

I never had a problem. And it works great for rifle bullets.

I think the question is more of price than hardness. Lead is the cheap part of bullet alloys. The tin and antimony are more, so mixing linotype with wheel weights or even pure lead reduces the price.

But I was buying linotype when it was not too expensive. And I bought a good bit.

I used to run a Linotype machine, in my younger days.

The 50 lb bar or ingot was called a 'pig', and was fed into the Linotype melting pot.
I should have learned casting, waaaaaaaaaay back when.
There was always Linotype 'slugs' (a line of type) and 'pigs' laying around the print shop. (At least 10 pigs. Never less.)

 

[platekiller]

Well a 410 brush and wipeout did the trick. Won't make that mistake again.

Here is a pic of the big pieces that came you.



That was no fun.
