One of the reasons I haven't invested in the 6.8mm SPC yet is that I don't think the improvements over 5.56 are enough to justify the investment. I would rather save the money and invest in a scout rifle in something .30cal range. I'd probably go .308 win or .300wsm. I would love a Styer scout, but will probably build up a Remington model 700 modified by Robar for M14 magazines, 16" barrel, etc. I was looking at springfields new M1a scout but I don't like the reciever (they look kinda cheap) and they are expensive.
