Leading in the chamber?

I’m a real amateur with pistols and reloading for them, so I’m not sure if this is a common problem or not.

I load for my 1911, 45 ACP. My load is 4.4 gr of titegroup under a 230 gr LRN. These bullets are supposed to be 18 bhn. Velocity is around 760 FPS.

I’ve never had a problem with leading in the barrel, but for some reason I get lead build up in the top of the chamber. It only takes about 200 rounds before it gets noticeable. It doesn’t cause feeding issues, but it is a real pain to remove it.

Is this a pistol issue or a problem with my reloads?
 
R your bullets undersize(less than .452?), r u seating too deeply, ru shaving the bullets while seating. Does your rifling start abruptly(ie no taper). If u have chromelined barrel, is it smooth at end of chamber-start of rifling? I seldom see leading in a 1911 of any brand. By (top of) do you mean 12 o'clock or end of chamber?
be well

Bullets are .452. I’m seating to 1.205”. Bullets are not shaving while seating.

There appears to my uneducated eye to be a taper to the start of the rifling.

The pistol is a Norinco and the barrel is factory. Maybe I have a cheap Chinese pistol problem? Haha.

The leading is at 12 O’clock. Nothing on the sides or bottom.

I too have a nork .45, and have no issues; I shoot lead 200 gr. SWCs. I also shoot lead out of my 9mm nork NZ85 and Jericho 40; no issues with them either. I do get a bit in the forcing cone on my GP100 .357, but am loading .38 special cases very light, and using 158 gr. SWC in those. A bit of lead in the chambers, but not much. All of my lead bullets are DRG.
 
Are you sure it is lead, as opposed to bullet libe residue. The 1911 has a steep feed ramp. The bullet from the feeding cartridge is being pushed in the chamber by the slide and hits the chamber wall at 12 o'clock, leaving bullet lube residue.

It’s definitely lead. I can peel it off with a dental pick.

Is the fouling in the leade area or in the area before the leade rifling starts?

What powder?

When I prep a new pistol, I polish the feedramp and the top of the chamber, because the bullet rubs there as it chambers from the mag.

All my Norcs were polished like that before I fired the first shot. maybe that was a good idea.

I polished the feed ramp when I first got it, I polished the top of the chamber today, hopefully that will help.
