[QUOTE="357Mag, post: 1819433, member: 106883"] Steve - Howdy ! The .243's built-in challenge to long barrel life is it's shallow shoulder angle. It also has a tad more case capacity than is really needed, to fit a lot of shooter's applications. The rise in popularity of newer factory and wildcat 6m cartridges like the 6X47L, 6XC, 6 Creedmoor et al; are evidence to those realities. The 6mm Remington case holds approx. gr more than does a .243Win, and we all see how well that case is doing. One would be challenged, if trying to give definite proof that a 6X47L-chambered would exhibit longer barrel like than a 6XC or 6 Creedmoor-chambered barrel. If your chosen 6mm bullet wt runs as high as 95gr, I'd recommend a 1-8 twist. With regards, 357Mag [/QUOTE]
