What can your 6.5 creedmore do that my .260 can't?

[hoytcanon]

Nice project HC. A Ruger mag box is 2.90" too isn't it?
Sounds like my 260 target rifle only heavier.

I have an M77 MKII stainless .260 with 22" barrel... that and my M77 MKII 6.5X55 will continue to be the hunting rifles, regardless of the results with the 6.5 CM.

 

[Hitzy]

That wasn’t the point. A bit of history on the Creedmoor.

http://www.65creedmoor.com/index.php?topic=5826.0

Just saying it would be a better cartridge had they used the 284Win as a parent instead of the 300 Savage/30TC...since they went so short, they should have went slightly fatter.
Doesn't change any of the original design parameters:

Superior ballistics. It needed to be as good as any safe hand loads being used in conventional high power competitions
Pricing comparable to match grade .308
Much lower recoil than a .308
Standard .308 magazine length
Not a barrel burner
Loaded version and components readily available should you take this to a large market
Recipe written on every box – avoid using proprietary powder.

Maybe you should call Hornady’s engineer and let him know.

Funny how the boys haven't answered you yet....

1) brass easily made from 308.
2) higher velocity with typical hunting bullets.
3) its not the new popular Fudd cartridge.

This is exactly why, unless you are outfitted for it, there is no good reason to go with the 260 over the 6.5 Creedmoor.

 

[LittleBoyLefty]

Ok, Chuck, I'm sold... I have an M77 MKII 6.5 CM on the way, Target/Laminate with 28" barrel... I will check it out for myself... I can say right off the top, I like the brass.

Those are very nice rifles. That dark gray finished metal just goes so well with the laminate. I expect it'll shoot half decent for you !

What're you scoping it with?

I think he was pointing out WHY the 260 is the better choice lol.

Details, details... Lol

I have two Leupolds in my shop, a VX-3 4.5-14X40 Varmint Hunters reticle and a VX-3 6.5-20X40 Fine Duplex... I think I will start with the 6.5-20 as I will only be punching paper with this rig. I agree that the target grey finish looks good with the grey laminate... I have had four other rifles in this configuration including the relatively rare .22 PPC and 6mm PPC (both of which I sold... like a bonehead), and one that I rebarreled to .22 BR, but they all had 26" barrels, this will be the first with a 28" barrel. All of the target configuration rifles have been very accurate shooters.

 

[chuck nelson]

I think he was pointing out WHY the 260 is the better choice lol.

And if that’s all you can come up with (you can also form CM cases from .308 brass) then it’s pretty obvious what your choice should be.

 

[Gatehouse]

The only reason to be forming cases for either cartridge is if you want to do it for some reason.

 

[chuck nelson]

Agreed.

Is there better brass than lapua?
