Barrel leading?

Post by Dr. Marneaus »

How much leading is normal in a smooth bore when shooing slugs? I understand that his is common it I don't know is being common means 'normal' or 'acceptable' I understand that a rifle slug has fins that are basically squished in the forcing fine and then squished at the choke. Is this normal? Does it affect anything?

I'm running improved cylinder so slugs should still be fine. I have run maybe. 10 slugs through the gun mixed with some buck and target. I can see lead all the way back at the forcing cone as well as a bunch at the muzzle.

I have read about removing this (steel wool, or I have a big 45 pad) on a cleaning brush with a drill or by hand), but is there a way to prevent it? I can see a decent amount of tooling marks inside my barrel from Remington, perhaps I should polish the barrel?

Let me upload some pics.

Never heard of barrel polishing. I think that leading is a normal process. Tornado brush is the best and the easiest way to remove barrel leading.

They are $4.99 on Brownells

When does leading become a problem? I ask because if I see that much with only 10 slugs down the barrel what happens when I go to training classes and have to run 50 or 100 slugs?

It depends on what you consider a "problem". I can't imagine a smoothbore barrel or IC choke leading up to the point where it causes damage or becomes unsafe. Pattern quality or consistency might suffer eventually, but for defensive/combat roles with buckshot and slugs, I doubt it'll be worth worrying about, if it's even noticeable.

If you don't like looking at it, just scrub out the bore with a brush and an appropriate solvent, it's not good to let crud sit in the barrel anyway. If you're worried about safety or performance, you probably don't need to be.

Good to know.

Just curious if it's bad, or causes accuracy or performance issues, or if it can become dangerous, etc.
