Re: 6.5mm Creedmoor vs 6.5x55mm

Quote:

Thanks. But what are actually realistic ballistics?

I did a quick search and found these two comparisons:

6.5 Creedmoor 129 gr 2950 fps at muzzle

vs

6.5 x 55 2700 fps at muzzle.

Now maybe that 6.5x55 is loaded down?

I've never tested my 6.5x55 with 140 gr FMJ bullets in the chronograph so don't even know the velocity it is getting. Maybe a little project.

I am asking for (semi) serious reasons. I was looking at an article of a "tactical" rifle based on the 6.5 mmm Creedmoor. Thought it looked cool, should I get one? Then "no way", I already have a 6.5x55 Mauser M96, which is fantastically accurate. Original stepped but cut off military barrel. Now restocked in a crappy black plastic stock.

Now I don't have any "tactical" rifles, and we are denied by our masters having anything serious in semi auto, though amazingly pump actions are still accessible. But if I wanted a tacticool rifle, my 6.5x55 could fit the bill ... until I wise up again and decide spending money on such a project is silly. But to me, the 6.5x55 nakes quite an ideal choice.

Interesting I was looking at a video of a European sniper rifle concept by CZ earlier this year and was surprised at the time to see it was based on the 6.5x55.




Case capacity per the Nosler manual for a 130 gr bullet is as follows:
52 grs for 6.5x55
47.1grs for 6.5 Creedmoor

Yes, I do believe the ballistics you show are loaded down..

Per what I have read up to this point..the creedmoor was designed for what it is
being primarily used for..target shooting...lets you load the bullets way out and still have a short-actioned rifle..as the article suggests in the previous post I put up..where as that is not possible with the 6.5x55..however now many are starting to also use the 6.5 Creemoor for hunting..every major rifle manufacturer has at least one and most have 3 or 4 models chambered for it..its low recoil, flat shooting, and the 6.5 has superior ballistics..kind of where the yin and yang meet..

I have a 6.5 Creedmoor in a Bergara --long range precision rifle..have not shot it that much yet..but what I have done with it, was extremely accurate..with factory ammo..let alone reloads...

Shot my 6 Creedmoor a couple weeks back that is in a Ruger Precision rifle..also very very accurate..with Hornady factory ammo--5 shots touching in a round cluster at 100yrds...

A newer range opened up about 30 minutes from where I live..targets to 1600 yards..plan to spend some time out there as time allows..
