I've owned 2 Zastava M70's, one a .375 that I had converted to a .375 Weatherby and the other which I currently own, a .458WM.
When I bought the .458 it was already on its second stock, the first splitting after 20 shots. I have since a Hogue stock fitted.
Another thing with the .458 is that even though it extracts empty cases fine, it doesn't eject them properly. The empties just fall back in the chamber and have to be removed by hand.
None of this is to say that Zastava's are a bad rifle - and indeed I like them, but just like many other rifles they need some fine tuning before they are 100%

Cheers,

You'll probably never NEED a gun. In fact I hope you never do. BUT IF you do, you will probably need it worse than anything you've ever needed before in your life...
