I bought my Engraved Brno ZKK 602 in 375 from the owner of Tradex. But I'm not familiar with the ZG-47. Would it be as good of a starting rifle for a custom project as say a Brno ZKK 601 or 602? Could it handle a magnum cartridge such as the 404 Jeffery? Or would to much material need to be removed? I'm not saying I want to do that, just wondering if I should pick a few of these up, as there reasonably priced.
