I went with the SR25 and Mk20... In 7.62.
IF I get into 6.5 it'll be to convert the SR25, simply because they use a 22" cut rifle bbl. Hard to go wrong with either one though and I wouldn't spend $6k on either unless it came with the scope. Well, ballparkish. Those are roughly $4500 rifles and are every bit as reliable as they are accurate. You may be able to get more accurate but I doubt you'll find a better combination of accuracy and reliability.
