Small add to the comments -
Accuracy wise - it’s the Brass spec to Chamber spec’s that make it accurate - meaning it’s NOT JUST the chamber spec.
Some of the best gunsmiths have known this for years and buy custom chamber reamers to keep these types of tolerances between the brass and the chamber.. couple it with precision chambering and you get a tack driver as long as the barrel is good..
Cartridge design wise - it’s making the brass optimal for shooting longer pills for longer distance accuracy (barrel makers jumped up twists as well) that are seated more optimally and still fit in the magazine..
But for accuracy the chamber to brass spec if most likely the biggest factor..

JB,
In a way the 6.5MM CM suceeded in spite of the early advertising.
I think it could be said it was the first round where SAAMI specs had chambers, throats, freebore, and ammo that delivered safety and very accurate rifles combined with twist rates that handled long bullets with decent to better than decent BCs.
There has never been a round so well designed that made it through SAAMI.
Add in low recoil and enough killing power.
Velocities fast enough to deliver decent trajectories but also good termial results from cup and core bullets.
The best Goldilocks round so far.[/quote]
All excellent points--and exactly what I found after actually using the round more than a little bit for the last dozen years!
In fact, as I've mentioned before, have continued to buy factory 6.5 Creedmoor rifles to see how well they shoot, especially with factory ammo. So far there's only been one disappointment, but suspect it was due to the the rifle's stock, as I just bought another of the same brand but with a much improved stock, and it shoots very well.
