Anyone reloading 5.7 x 28?

Good info here: https://www.fivesevenforum.com/
Problem I've seen is the protective coating on the cases gets rubbed off the cases when sizing and is essential for the brass to stick to the chamber walls upon firing. Also with a blowback action, the slide starts moving backwards while the bullet is traveling down the bore which results in the cases being blown forward and elongating. Fired cases won't fit back into the chamber without lots of resizing.

Exactly what I was looking for. Thanks.
