Using what you have chosen as a basis for comparison, I agree - everything you say is correct. No .308 shooting 155g Palma bullets or 168g Match Kings will ever match the 6.5 Creedmoor with 140g match bullets for downrange performance. That's not the point I was trying to make.

When we match B.C. for B.C. and velocity for velocity, bore diameter makes no difference in trajectory or wind drift. I was pointing out that to accomplish this with a .30 caliber, we have to go up to the .300 Win Mag and very heavy bullets, like 220g - and few will want to get hammered by a load like that out of a rifle similar in weight to what is available in the 6.5's.

There is no shortage of rifles chambered in .300 Win Mag. Their standard 1:10" twist handles these bullets easily. Many platforms that are available in the 6.5 Creedmoor are also available in the .300 Win mag. It remains a very popular long range match or "tactical" choice, at least for those who can both put up with its recoil and might actually be trying to kill something (or someone) way out there. I believe our armed forces have even begun phasing out the .338 Lapua in favor of their .300 Win Mag in the Mk248 Mod 1 configuration - with the 220 grain bullet.
