Fit, fit, fit.
Diameter of bullet. What is his diameter pre- and post-seating? Is he swaging the bullet diameter down?
Next, get a softer alloy (8-12 BHN). Unless he casts himself, he probably has an 18-22 BHN bullet.
A clue to what is causing the leading is where the leading first begins to appear.
If it appears near the chamber, chances are that bullet diameter or hardness are the cause. A diameter too small or an alloy too hard will allow high pressure gas to leak past the bullet, which erodes the bullet and leaves leading near the chamber.
If the leading first appears on the leading edge of the rifling (if you imagine the bullet being pushed through the barrel, you will note that one edge of the rifling does most of the work of imparting a spin to the bullet. This is the edge you see when you look through the barrel from the breech end), the bullet might be too soft or the velocity too high.
If the leading appears in the second (front) half of the barrel, the bullet is running out of lube.

HI Gang;
            I have done all the right thing to reload bullets and sometimes it is good and sometimes it is not. I have a brass curly pot scrubber that I cut off some and wrap it around a bore brush to remove the lead.
  I reuse the ones that work and avoid the others unless the price is to good.
Life and shooting is to short to stress too much, "when its time to shoot, just shoot "

Yep, a Lewis Lead Remover is a very handy lead eraser, too!

We all put different amounts of care into making our ammo.  We all should realize that some "just load" and some "want it perfect".   In the end, what really matters is:  "Each to his own way of having fun!"

Good luck, GJ

I think his gun is gummed up from the lube.  That seems to be the only thing that gets mine gun to get sticky.  Same way a .22 does and for the same reason.  I run Oregon Trail 230 round nose with no problem except the gun gets gummy after a couple thousand rounds.  I can lube it and it will keep running but I think the build up is hard on the gun as far as tolerances.  I use Vihta Vuori N-320 which I think is the best there is.  I have tried everything as far as powder.  I can soft brush the chamber clean and have no leading that I can see.  I get what I think is lube build up on the slide.  I am going to start cleaning after 500 to 1,000 rds now as I think it is easier on the gun.  I have gone over 3,000 by squirting oil on things when they get sticky.
