These are Berdan-primed cases, and almost impossible to reload. I was never planning on reloading the brass because of that.
Couple of things to try with your M1911 clone. If you suspect slide/frame battering, get a plastic buffer that goes on the recoil spring guide should provide some cushion.
After a thorough cleaning and degreasing, if you see areas if excessive wear, try some Nanolube, and see if it will remove enough metal to stop the wear. For instance, use some on the frame rails and slide, and cycle the slide a few dozen times to see if it then moves freely.
Some of the smaller parts, if showing excessive wear, could be replaced with higher-quality items. A critical set of parts is the sear and disconnector. Brand-name versions machined from hardened tool steel should cost about $40 for the pair. I'm putting them in my clones as part of my preventative maintenance program. If you have the handgun torn down completely, it's a good opportunity to swap out some of the smaller parts for quality versions you can trust.
There are also "rebuild kits" that contain every small part and spring. Even if you don't use all the parts at once, it's a good way of getting enough spares at a better price, for later use.
