[QUOTE="nicholasjohn, post: 1811700, member: 109113"] I think you've got the answer. The 6.5's have always used fast-twist barrels ( to stabilize the 156-160 grain round-nosed bullets ) and what's really going on here isn't a 6.5 thing - it's the long & heavy bullets that improve downrange performance that everybody is after - not that particular bullet diameter. If the 270 or 7mm had was set up in a fast-twist barrel, it would do the same thing. It's just that the 6.5's have always been done that way, so they got a head start on the other bullet diameters. Now everybody is having custom builds to do the same thing with the other bullet diameters, and the bullet manufacturers are slowly rising to the occasion with long-for-caliber, high-BC bullets. If the 30/06 had originally been set up in 1-in-8 twist barrels, and really heavy spitzers, then the 30-calibers would be the one enjoying this huge popularity. As it is, they are just now catching the wave. Before too long, I think we'll be seeing long & heavy bullets for ALL the commonly used bullet diameters, and fast-twist barrels to shoot them through on factory rifles. It's kind of ironic that the bullet diameter that was once the least popular caliber in this country has been the one that led the parade in this movement. [/QUOTE]
