Re: AR10 cartridge choice help

6.5 Creed. 260 ballistics without intruding on the powder space due to the 2.850" mag length. 6.5X47 Lapua is a good one too but it's pretty spendy brass to be spittin' out of an AR. One thing you should mention is what do you want to do with it? Heavy 24" barrel or a lighter profile, fluted? A lot depends on your plans for use. 308 is a good all-around, 6.5's are great ballistically with enough juice for hunting, 338 Federal is another hunting round although shorter range. Also the 6mm Creed would be as good as the 243 but something different and allow the use of longer higher bc bullets without seating below the neck and less recoil with a great trajectory. Lots of options, just what do you want the rifle to do?

24" varmint barrel fluted looking for a 800 yard gun, white tail to 600 yards possibly

a lot of votes for the 6.5 creed. I will for sure look into that more. the SAUM rounds still peak my interest also.

Re: AR10 cartridge choice help

So I've decided that I don't want the recoil of the SAUM rounds because I want a very quick follow up shot if need be. I know I know but hey we all miss the wind or something from time to time and I plan to hunt yotes with this rifle so might have to hit one on the run.

That being said now what about 6.5 creed vs 6mm creed vs 6.5x47 lapua vs 6x47 lapua? I don't want a standard 308 because I do plan to get a very basic 308 upper for a SHTF upper. I do like the more non standard rounds I guess I just like to be a little different.

Re: AR10 cartridge choice help

Boils down to cost of components. Lapua or Hornady brass, the Creed is short enough to take advantage of any bullet, the Lapua is better with 130's and below and runs a little slower (this is with 6.5's) Either one in 6mm has enough powder to run the 105's and such and will shoot just as well. I've seen factory dies for the 6X47 Lapua, not sure if the Creed has caught up yet with the factory offerings but I'm sure they're available.

Same same, Creed has a little more case capacity and cheeper brass (but is still is considered very good quality).

Can't go wrong either way but personally on the 10 platform I'd go with Hornady's version. I don't have one, but I do have both 6mmX47 Lapua and the 6.5X47 Lapua but both of those sit in bolt actions (they shoot very well too).

I plan on building two (maybe three) uppers for my AR10, one is a 6.5 something, most likely the Creed, and one in a lighter weight 18-20" bbl in 338 Federal of 358 Win for hogs and big game in thicker stuff. Of course it seems silly not to have a 308 so maybe I'll have to have that too, but the others will come first as they'll have more use for me.
