That's good advice. One of my 7x57s is a Zastava M98, basically the same thing as the Mark X, with a 1:220mm/1:866" twist. It handles long 175-grain bullets very, very well. You can also find some pretty good deals on older XTRs. As mentioned all over the 'fire, they are about the most underrated M70 there is.
"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
