Too much crimp, but it shouldn't hurt anything, as long as you're not maxing out your powder. A really heavy crimp like that can drive up pressure. I pulled some CorBon .40S&W 135gr JHPs, and those bullets looked even worse than yours. So they REALLY crimped them, and that's factory CorBon. Basically what I'm saying is you were crimping more than necessary, but it's not like problems will definitely result. If you go too far head spacing issues could result. The bullets are fine to shoot again, but you will almost certainly have to apply that same amount of crimp. Anything less will not fill in that cannelure you just made.
