Finally an update! All of my mags work great after I tuned them using calipers and channel locks.
I measured the width of the feed lips in three places, the front, middle, and back. Below are pics.
First, mag placed in channel locks and bend slightly, then measure:
The front section measures about .457
The middle section measures about .41
The back section measures about .39
The four mags I did are all within a few thousandths in these measurements and run smooth. It seems like the front and middle measurements are most important, I had one mag where the middle and back were fine, but the front was too narrow by one hundredth and it did not cycle well. I'm using factory FMJ and HP ammo, all works well.
I did not do anything else, no polishing the insides or anything like that. Before these modifications almost every round would nosedive into the feed ramp and stick, now they don't. I hope this helps anyone else looking for help on this.
