You are right I would not expect the M14 in just about any caliber to be the equal of a quality bolt gun in the accuracy department due to the sheer design, nature of the M14. Lots of moving parts when shooting, like a helicopter, being a loose collection of parts all trying to go in the same direction, shake rattle and roll. If I were younger, no chance of that, and just starting out for long range shooting I would go with the 6.5 Creedmore, bolt rifle, even though the 308 has been very good to me over the years, but it has it's limitations. I certainly can't claim that I have reached the level of limits with the 308 for I would have to live another lifetime.
