Huntz, if you look at PRS caliber usage, it appears to me that the 6mms have already overtaken the 6.5s. So for competition, I think so. For hunting and the casual competitor, the 6.5s still make sense. The 7mm08 used to be the hot chambering in the high power silhouette game until David Tubb started using a 6mm. How he took down rams at 500 meters, I don't know. They must not have been set as heavy as the ones I shot at.
