Well can't help you on that, but I can throw a few ideas out,

Depending on the alloy and temp you might have been getting some a bit on the large size, this and running them through a standard type lube sizer, could have possibly wiped the lube rings off. Or even if running them through a standard lube sizer didn't wipe the rings it might not have put enough lube on them and you experienced some leading.

As far as KH'ing, nope haven't seen that with any I have shot so far. But like mentioned I'm not shooting them overly far to begin with. I'm running a standard Colt Govt 1911, right out of the box. The only issues I have had were finding some that didn't pass the plunk test. A little bit of looking really hard and I found two things, first I wasn't seating them quite deep enough for my chamber, and the other thing was the crimp wasn't quite laying the lip of the case down enough. They were just dragging the inside of the chamber enough to not let the action close. I seated the longer ones a bit deeper and ran the others into the FCD die just enough to catch about the first 3/16 to 1/4" of the case and all was well.

also if you haven't tried the 45/45/10 lube it works great, and now White Label lubes is sell it pre-made so it is MUCH easier to use since you don't actually ahve to mix it up yourself. I have about a pint or so left of my last batch and when I use it up I will probably purchase some of it to give a try myself. Anyway you slice it it should beat sitting there stirring for half an hour and stinking up the shop.
