As others here, I have used the KB-107’s a few times with excellent results and zero problems. I also don’t push a Hyper slug to the limits with ridiculous expectations and punishing environments above and beyond the recommendations of the manufacturer.Good info, thanks. Feeling better about them.
I’m not running a 13-1 plus mill with a 300 shot in a race car. Is it possible? Sure, though at this level, give me a forged slug and relieve me of any worry.
