Leading in the barrel

Post by Multiracer on 9/29/2017, 8:07 pm

I have a Kart 45 NM barrel that leads in the chamber as well as the first inch in areas.
It is really stubborn to clean.
Any recipe ideas so I don't over scrub with the brushes ?
I shoot, jacketed, swaged and cast bullets virtually all the time.

I soak my barrels in Kroil over night.

I have an Outers Foul-out system. Unfortunately, they were discontinued and the chemicals are no longer available. Kroil is also good. I have the spray can. I shoot some in the barrel and let it soak 20-30 minutes, then run a brush through it.

try some JB bore paste  in my 45 I run 50cal  nylon then hoppes and let it soak wile cleaning rest of gun then more hopes and then JB bore paste and repeat till clean then do this after each match and it seams to clean up easier if I use the JB,s every time.

A while back there was a debate about the use of JB bore cleaner. I believe that the primary poster was Jerry Keefer so the thread might have been removed. Might want to do a search. Interesting thread with a lot of pro & con on it.

I would look at your components and reloading technique to stop the leading.

Are the bullets you bought actually the size you expected?
If you can, slug your barrel.  Your lead bullets should be .001-.002 bigger than the grooves in your barrel (not the lands).  If they aren't you will get leading.

How about the Lewis Lead Remover? I've never tried it in .45 barrel, but it works great with my .38 revolvers and S&W 52.

Is it leading full circumference of bore or just the bottom? How far out are you seating the lead bullet shoulder? Should be approx. 0.020"-0.030" of bullet shoulder sticking out of case. Can you measure from rear of hood to the front edge of chamber (headspace)? Depending on who built the pistol they might not have finish reamed the chamber. They have a tendency to lead. Also swaged bullets have a tendency to lead some barrels more than others.

Mostly the bottom, near the ramp, bullet shoulders are about what you stated for almost all of my ammunition.
I will measure the headspace when I get back home this evening.
I probably use more swaged than anything.
Thanks for the tips guys, I appreciate it before I destroy a good barrel.

while I don't have any leading issues with hard cast bullets,  swaged will leave the type of leading you described.  Try simply coating them with 45-45-10 via a tumbling method.. cured it for me

Thanks for info. Bottom only is typical of swaged bullets. Try shooting cast only and see how it goes. I have a pistol that I will not use swaged bullets because it takes an hour to clean it. Doesn't lead with cast!

Funny you mention that stuff. I just got a quart for some other bullets. I will try coating everything I load.

Bullet size, lube and lead hardness all play a role. There's a cast bullet forum with tons of info for both rifle and pistol.

http://castboolits.gunloads.com/forum.php

What I do is use bore foam, let it soak for an hour or so, then use Hoppe's and a 45 rifle brush or a 45 military brush.  A couple of good hearty scrubbings with that big brush will get the lead out.

Barrel leading: All good advice here. Bullet fit critical. Swaged bullets around 700 FPS with your loads with these or expect leading, Mechanical lead extraction works best (quicker), use a worn copper brush of bore size wind a little Chore girl/boy pure copper (unwind the strands from a pad to use) make it a tight fit in the chamber ( some force is required to get started and use so get a good grip or use other means to hold the gun stroke the brush through the tight spot where the lead is pull it back then repeat until the stroking becomes easy remove the brush run a dry patch through and have a look, likely the lead will be removed, if not repeat the procedure, clean as per usual. The whole thing only requires a few minuets, does NOT harm the bore and helps put a smile on your face at finding a solution to a difficult (formerly) problem. I used to shoot revolvers a lot daily and nearly gave it up until finding this de-leading method. A snuggly fitting paper patch will show you where the lead is in a barrel without the need to examined it further, it will glide through a clean bore but catch on any lead in there. Sorry about the long post. PhilMcC

Jon,
Not having a go/no go gauge, the measurement I get is .901 " Just about right from what I read.
I am going to chalk it up to swaged bullets and get after the cleaning cycle a bit earlier.

0.901 is good. Does the lead from chamber to rifling have an angle leading into lands?
Thx

You might be shaving the bullet a bit during seating , especially if not cast perfectly . I had a similar problem with 200 gr  swc cast ,
Switched to zeros 185 swaged , problem solved .
