Problem with excessive leading

I've noticed, that the barrel of my Para 14-45 gets excessively leaded in comparison with other 1911 types I've owned. I fired a lots of .451, 225 gr. LFP, loaded with 4.4 gr. of 700X through other barrels, however haven't seen so much lead in any of them. Para's barrel gets dirty right at the beginning of the rifled part of the pipe. Just wondering how to remedy the problem, besides switching to FMJ's ?

Try a slightly larger bullet and a diff. lube, alot of the lube is not very effective and is used because it doesn't mess up the bullets during sale/delivery.
 
Lee Lube

Lee Alox on lead which has wax lube allows me to warm up charges considerably before leading starts. If it still is a problem, a little copper "Chore Boy" wrapped around a brush or patch will take it out in a second at the range.
 
We are amazed at the new lubes we have been trying, at all velocities common to cast bullets we are not getting leading, in fact sometimes the barrels are cleaner then when we started! Of course we still must use a bullet that is of the right hardness and bore size. A hard bullet that is a little small is worst then a soft bullet that is a little small. We used some Wolf reloaded ammo as a control ammo and from the outset out grouped it 4-1, we used our loads to clean up the mess the Wolf bullets left in our barrels, we retrieved the Wolf bullets and found that all the hard lube they used stayed on the bullet!! Lesson here is to experiment and try diff. things until you at least start in the right direction.
 
It could be that your para 14-45 has a tighter bore than your other 1911 types. Some guns are built differently. Some of my 45ACP’s fire factory ammo at 950 fps and my STI sends it down range at 1050fps, same box of bullets.
Read up on slugging your bore with a bullet and then measure the dia of the grooves in the bullet, against the outside dia of a new bullet. If the difference is great you might have to find a smaller dia bullet.
I ran into this one time with an order of 5000 bullets and I solved it by buying a Lee bullet resizer in .451 and resized them, then relubed them and they shot quite well after that.
 
Vic1 :

A "Chore Boy" is a pot scrubber used in the kitchen to clean really dirty dishes - your mom likely used one. It is a copper woven pad and can be found in any kitchen supply place or dollar store - three for a dollar maybe. Just unravel a long string of it and wrap it around any patch, brush or swab and run it through the barrel. It takes almost all the lead out in a second. The copper Chore Boy treatment is super fast and is all I need to bring accuracy and velocities back to normal.

For absolute cleaning, a 50 /50 mix of vinegar and hydrogen peroxide left in the bore for 5 minutes will clean it . Use an earplug to plug one end and syringe it full - leave for a short time, then pour it out and swab it out. Don't let the mixture get on blueing! It doesn't bother stainless.

Maybe use a paintbrush with just a little oil on it to give the gun a going over in all the nooks and crannys . The paintbrush works really well around scope mounts, sights and such too - before or after a hunt.
 
I agree with above comment. The .45acp lead bullet should be sized .452 NOT .451 as with jacketed. Para barrels are known to be very good and are the correct grove diameter at .451.

Where is the leading occurring. In the first 1/2" or towards the muzzle?

If you are not already use a soft lube. Softer bullets is a better cure than harder in this cartridge.

Take Care
