Most bang for the buck is in my opinion the CZ550's. I have been using Mdl 70's since gunsmith school in the 50'2 and they are absolutely my all time pick but I also like the CZ's and currently have a 375 602 and a 416Rigby 550 and have absolutely NO complaints about them. I do like the older 602 stocks better than the 550 but that's just a personal fit thing on the factory stock. As a big bore I actually believe they are a better basis for building a custom rifle. In the final analysis it is really a personal thing.
