Let's be clear, unlike yourself, I don't enter this discussion with an agenda. So do not accuse me of being intentionally misleading. Mmmkay? The reason I may have a 'thing' for the 6.5CM is because I first had a 'thing' for the 6.5x55 hunting rifles, 30yrs ago and the .260 20yrs ago.You see! unfamiliar with, or wish to mislead readers about, the 6.5x55 and the rifles in which it is chambered.
The Swedish Mauser has a 1:7.55 twist. It was designed to stabilize 160 grs bullets. No "customization" is required in a commercial rifle chambered in 6 .5x55 to match 6.5CM performance of it chambered to CIP specs. The only "customization" to a Swedish Mauser required to meet or exceed 6 .5CM performance is to drill and tap for scope mounts, admittedly an undesirable approach.
The 6.5 CM was designed to allow a short action rifle to use VLD bullets. Bolt throw is immaterial. So perhaps for weight savings? Makes sense in a hunting rifle. None in a target rifle.
The 6.5x55 is a 46,000CUP cartridge and it requires a long action. One of the design parameters for the 6.5CM was that it work through an AR10 platform. Can't do that with the overly long and lean 6.5x55. You do not think it is a step forward to duplicate long action performance in a much shorter case? I do. I think we've learned a thing or two in the last +120yrs.
