The 6.5x55 is a great caliber so whats the fuss about with the creedmoor is it that much better?

I consider them to be essentially identical in performance, but I've heard the Creedmoor possibly works the brass less hard.
And the Creedmoor fits in a short action which is a bonus.
Other than that I don't see what the fuss is about either, probably just advertising hype to sell it.

The 6.5 x 55 is an accurate, versatile cartridge but requires a longer action. It has been around since 1894 and is still commercially available, that should say something about it. The Creedmoor was devised a bit over 10 years ago with a specific intended purpose. ( long range target shooting ) It has been shown to excel at that and is also a very handy hunting round as well. Only time will tell if it has the longevity of the "Swede".
By the way, I own and shoot rifles in both chamberings.

I don't follow high power too closely but it seems to be rapidly wiping out 308/7.62 NATO rifles in competition circles. There is some stuff that is a fad, but I don't think this is one.

Because of the Creedmoor cartridge or just because of the 6.5mm bullet though?

These would be gas guns I presume. If the do work well I am a little surprised as a 140 Lapua loaded in 6.5 Creedmoor to max length (which I guess is somewhat limited by magazine length rather than throat length and getting close to or on the lands. Hope that makes sense) is pretty long ie the projectile is nearly or at least 2/3 as long as the case.
sungazer wrote:Thanks a great explanation I can visualize what you are saying without too much actual time spent with or looking at them. I was just curious how the 6.5 held up to rhe rough handling a semi can give the cartridge if contcentricity ever suffered due to a knock. Different manufactures have different chamber dimensions with all factory chambers a bit on the long side to cater for the longest bullet ever expected and then some to keep pressure down should the user load a hot round. Do you find very large chambers in the Ar's I am sure that many people get custom barrels made to help with accuracy as well? just as we do with bolt actions.
After having a quick look at the first Utube I can see that custom barrels long target barrels are fitted.
I cant look at a lot of video due to my internet connection limits.

Also 55 requires ~44gn of 2209 to push 140gn @2617 ftsec
Creed requires 40gn of 2209 to push 140gn @2660 ftsec.
I'm sure there's results to the contrary but similar performance from less Powder is good.
62000psi Vs 51000psi saami will do that
