[QUOTE="QuietTexan, post: 2411977, member: 116181"] All the large capacity anythings are barrel burners, there's nothing unique about the 6.5mm bore in that regard. Look at many classic calibers - the 7mm Rem Mag is one of the most overbore factory chambers made, the 25-06 is right behind it, then the 243 Win is chasing them as worse than the 22-250. Run any of them hot and you can kiss the barrel goodbye. 6.5mm is just the popular bore right now because of the high-BC potential. But 7mm is still arguably the best in terms of pure ballistics. 6mm is making a leap forward for lower recoil for self shot spotting. Lot's of niche development happening on parallel tracks is muddling decisions because of competing goals. Useable barrel life is dropping anyway because accuracy standards are changing - guy who used to accept minute of pie plate from a hunting rifle are demanding off the rack guns shoot out to 600+ yards sub-MOA. Their barrels won't survive old cleaning methods and mistreatment as long not because any thing has actually changed, just they used to accept a lower accuracy standard for longer. [/QUOTE]
