Hello everyone!
I've been successfully reloading 5.7 now for the past few weeks and have had quite a bit of success in the pistol.
I've been reloading 1x brass with ~5.0 of True Blue and a 50 gr bullet. Worked up from 4.0 gr with iffy/weak cycling. Firm recoil now, feels good.
Light primer cratering, and ~50% of the brass showed signs of neck separation. (Shiny Band) some of the 1x 197 even showed banding, and I think I should throw them away? A little bummed, thought it was tougher than this. Hear people getting ~5 reloads. Maybe a lighter bullet is easier on it? I also think TB has initially too high of a pressure spike, but still burns too slow, producing a huge muzzle flash, what's a better speed powder?
Thankfully we got Jay to save us with this stronger brass. I got 400? I was gonna give a go soon.
I was hoping I might be able to get a cutaway of both brass to see the changes in the sidewall construction.
I'm guessing because of the lower case capacity I should reduce loads by ~25%? To start out.
Anyway, comments and advice is much appreciated.

You can kind of see it in my video.

Let's see pictures of your brass. I've got some that appears to have a band forming at the shoulder/neck junction, but it turned out to be lacquer damage right at that point, brass was fine. Maybe you've got something similar going on.
