mr. 10 glocks: that is interesting. in the picture you posted, it appears that the un-machined portion just ahead of the bolt sleeve shows that the bolt was cast and there's nothing wrong with that. However, if they are actually a one piece bolt, I am surprised that Winchester isn't telling folks that just as Ruger does in their M77. In Otteson's book "The Bolt Action" he describes in detail the process Winchester developed to attach the handle to the bolt. I have never heard any other source mention that at some point they started using a true one piece bolt. I just looked on their webpage for 2021 models where they go into some detail describing the M70 and there's no mention of it.
