To me it would depend on if I wanted a project or I wanted a using gun with little or no work needed. As the basis for a slightly improved to a full blown custom the Zastava would get the nod. For a using unmodified rifle then the Winchester PF. Caliber I like them all but the 6.5x55, 7x57 and then 308 are my preference in that order. This could easily change if I had a stockpile of components for any of them, which I do for the 6.5x55 and .308 but not currently the 7x57.
