I just got one off of my uncle, its a 30-06 that's been highly modified, with the barreled action being slimmed down, and a custom stock installed. Mine shoots very well, concidering, when I was picking it up, my uncle said it never shot all that well, and my dad reiterated the same. I just threw together some loads, and started banging out 1,25" groups.
I would say that for a stock rifle don't pay any more than $300.00; ther good guns, but I would say that there not worth much more than that...........and no, they are not winchesters 710; more like the 788.
The model 71 has a cilindrical reciever, a trigger mounted safety, and is shorter than a model 70. It may share an extractor with a post 64 winchester, as well as the bolt stop, but that is where the simularities end.
