    Thanks!
    I don't have the problem so much anymore, but when I did, Choreboy cleaning pads worked great. Get the brass- or copper-colored one, not the stainless steel version, so you don't scratch your barrel.

    Take the Choreboy pad and start cutting it up into roughly 1x1-inch squares (or whatever size works best with your gear), and put an old, worn out bronze brush on your cleaning rod, wrap the choreboy square around the top of the brush, apply solvent if you want, and push your rod through the entire length of the barrel, back and forth, back and forth.

    In a heavily leaded barrel, you should start to see slivers of lead falling out onto your work surface. Use bigger squares of choreboy if your brush is really worn out. You should have to use a fair amount of pressure to push the rod through, otherwise you don't get good cutting action out of the choreboy.

    I don't have to do this anymore though, now that I upped my powder charge a little.

    I was surprised to discover that when I first started reloading too... that more pressure could = less leading. I figured it would be the opposite (more pressure = more leading).

    I was getting some terrible leading in my 1911 barrel when running 200gr LSWC with 5.0 grains (or less) of Winchester 231. As soon as I bumped up my charge to 5.2 grains, my leading practically disappeared.

    I still don't understand how that works. It just seems like the opposite of common sense. You'd think higher pressure would mean more "smearing", but that's not what happens...

      xrmike -- more pressure, less leading -- under certain conditions the higher pressure upsets the bullet, filling the bore and sealing off the hot gas leakage.

        Ill try pushing them a little bit harder. I was using Clays but just bought some bullseye for my 9mm loads. That stuff is awesome! The clays made me feel like I was shooting a black powder musket with all the smoke and unburned powder, but the Bullseye is smooth and clean.

        As far as lube goes, I was always told that the lube was for sizing and didnt do anything for actual shooting. Wrong? I have a bunch of the Lee Liquid Alox. Last time I lubed bullets with it I applied the lube as the instructions said and let them dry overnight. They came out really sticky and they would get dirty so I wouldn't use them for fear of barrel damage.

          I've been shooting LEE cast 230 gr RN with a hardness around 14, 45acp with 4grs of clays and have had very little leading. Tumble lube bullet, LEE alox lube. I tumble then lay the bullets on foil then roll them every once in a while for two or three days to get a nice uniform coating. That alox lube takes many days to properly dry IMO, not to mention it gets on everything. No lead though.

            You need to lube your bullets, I bet that will solve your problem.

              I use a copper brush a few times, and then a steel brush at the end. gets everything out for me.

                Oh yeah, I read this article waaay back in the days so I cant remember very well and since I dont have issues I dont have these signs...but basically it said that if you see leading near the chamber that means your load is too hot or too low, if you see leading near the end of muzzle your running out of lube too quickly...that or the other way around.. forgot.

                    Well I went and pulled some of the bullets from the batch that caused alot of the leading.

                    Bullets were nearly all between .444 and .449, WAY undersized!
                    I then measured a newly cast bullet that hadn't been sized-came out to .455, sized came out right at .452. I then measured about 100 bullets that had been cast/sized, but not loaded and these were all .451-.453.

                    Can crimping these bullets inadvertently reside the bullets to a smaller size? Its the only way i can figure they "shrank".

                        Carnac is correct yet again. I just tested it. I complete removed the adjusting piece of the factory crimp die and loaded a bullet. With no crimp this thing sized a .452 bullet down to .448.
                        Without using the crimp die my bullets all get pushed back into the case. What to do?
