I like the idea of the shorter fatter cartridges, but the theory of more accuracy due to powder burn etc just seems like a stretch to me. I can use a fast burn or a slower burn powder when I reload and so can the manufacturer and in doing so get all the burn as early or late as needed.

As far as accuracy goes...perhaps the 308 has the possibility of being better (not proven by anyone I've seen)...but this week my tikka 30-06 put 10 rounds inside 5/8" at 100 yards. If the tikka 308 tops that....I doubt it will be by enough to measure. There are so many things that go into putting a small group together that I seriously doubt that the case diameter would produce a difference in group size that could be measured consistantly. Back in the day when you couldn't tailor your powder to the case as much as these days...I would believe it. But today, I just can't wrap my head around it...and those smarter than me have yet to prove it to me.
