I have an affinity for abusing rifles in humid dirty environments.
But I’m not sure how you’d measure the effectiveness of a bolt carrier. Nor do I think the carrier itself is subjected to that much stress anyway.

I don't believe the bolts are forged. There are some pretty good videos showing an automated lathe/mill pumping bolts out. "Wire" bigger than the bolt lug OD feeds through the headstock, then the lugs broached, face turned, then body turned, if I recall.
As Bill Alexander has said more than once... "It's all in the heat-treat". Good material is the starting point, but even very good materials fail in bolts without proper heat treat. That applies to C158, 9310, whatever.
Nothing to it with the right machine. https://www.youtube.com/watch?v=Nkn3P2Z5m5U
I'd love to test one but with several rifles needing shooting I'm not sure I could do it, however after a little testing by me I might be able to runt it in some students' rifles this summer and get potentially much more than 1000 rounds on one.
I think if you ran 10,000 rounds with one of these you'd see very little wear...just like with every other carrier out there.
