    99% of what I shoot are cast lead bullets and the crud scraped off the stop shoulder seems to be a mix of lead shavings and bullet lube. Suspect jacket and plated bullets wouldn't cause any such build-up.

    Well! Any replies yet? I'm getting back into shooting/loading my 1911s and remember all this misadventure when I started loading on my own pre internet!

    I've found there is no substitute for a plunk test! I bought a Lyman case gage and it's about worthless when compared to real chambers.

    I do agree with all of the above as described . If your .45 Acp 1911 is one of the Original military configurations . I had the exact same thing . It was originally designed for a 230 gr hard ball bullet . These being copper [ or even hard cast now in use ] will work. I tried using Everything lower in gr weight & design in both round nose copper FMJ's and SWC's .. NO Go

    No go & the exact same thing with fitting flush with the chamber in 200 gr / 185 gr . The round nosed
    bullets in 230 gr FMJ's work every time in mine . Your latter 1911's will also accept JHP's and mine will not !

    The 'sweet spot' for my military Rem' Rand is 0.250 OA 'Cartridge' . My original magazine I changed to a Wilson Combat [ 925 ] & also a Tripp mag Government model with the new hybrid follower . Perfect now ! . Mine does Not Like Any Lead bullets , under 230 gr .

    Re the Drop Test , The lower lead gr. wt SWC's are ok just dropping them in . Now However with the feed angle , they catch on the top edge of the barrel and are dented in upon feeding them normally .
    Mine is an upgraded Competition 1911 with close specs . YMMV .. Thanks !

    Check the leade in your chamber.If it’s an abrupt transition you will have a heck of a time with cast bullets. Reaming th chamber will fix it.

    In case there's any question about what the leade is, here's an illustration of the SAAMI one for the 45 Auto:
