That is a very broad statement. I do not know any facts to say otherwise, but I supposed you have enough experience with the Mauser vs R700 to base this on. Like you tested 30 designs of each with the only difference being the receiver and R700 variants shoot better. As far as more horsepower at higher cost, isn't that the fact in everything, not just rifles?It just seems to me that Mauser and its modern variants are just not as accurate as R700 and its variants. Maybe it's the round receivers vs flat bottom receivers. But I know all my R700's when pillar bedded shoot lights out without doing a whole lot more. Weatherbys just usually provide a whole lot more horsepower at a high cost.
