The M77, since it's conversion to CRF, was always marginal profit due to the fact that a CRF action is far more costly to produce than push feed.
I'm not buying that one single bit.
Ruger's "CRF," both MKII and Hawkeye, is just the original MKII action with the front bottom lip of the bolt ground flush to the bolt face. It was a simple conversion, and a lot of us did it before the CRF model was available from the factory. I'm also not buying the MKII action was any more expensive to produce than the original M77 action. I'd bet it was more economical to produce than the original M77 tang safety PF action with adjustable trigger.
