After awhile the nickle flakes off, flakes off faster the hotter you load them. I like R-P brand brass for reloading the 40 S&W, it has given me less problems than any other brand.
I have used it for 10mm but like Starline better.
Nickle brass does not seem to last as long as plain brass but I believe the nickling process hardens the brass.
Have a Nice Day
