Within limits, that is all I have found. 260's shoot just as well as Creedmoors if the rifles are built to the same specs. so do 6.5x55's. 65/06's seems to shoot just the same as 6.5x284's. Now, when rifles are built to different specifications, performance is likely to vary and this is the advantage the Creedmoor has. It was conceived a an accuracy cartridge and all rifles built for it benefit from that. This is especially so regarding ammunition, I suspect. GD
