I bought a 6.5CM AR10 but don’t have any other guns in 6.5 so I and way behind the ammo power curve. Assuming I will someday be able to find some ammo in stock, what is the preferred round or rounds I should be looking at for accuracy/competition use. I may end up building a bolt gun in 6.5 so a round that I could use with both would be great.
 
130gr or 140gr.
Barrel length and twist rate may favor one over the other.
Hornady American Gunner 140gr BTHP was a cheaper option before with a good track record.
FGMM 140gr Sierra, or 130gr Berger as well as Hornday Match 140gr have been ok in mine. I haven't tried the cheaper stuff like Privi, or S&B.

Best of luck finding any right now especially in any quantity.

I found Berger 130gr and 140gr ammo to be the most consistent and accurate factory ammo on the market. Good luck finding any right now, as I had issues keeping enough around 2yrs ago. The Berger ammo was better than Copper Creek, Hornady, or Prime. Granted I haven’t tried Primes newer offerings since their separation from RUAG.

Creedmoor components come in stock enough that it wouldn’t concern me right now trying to kit up to reload for 6.5CM.

If you are serious about quality ammo I would contact @FCS and see what he can do for you.
 
Maybe it's just me, but I've found that the Berger 140gr Hybrid Target is super accurate in 6.5-CM ... more so than the 140's and 147's from Hornady.

I agree but so far only in bolts guns. They are pretty hot and they trashed my firing pin in my ar10. Unless you have an adjustable gas block, I wouldn’t shoot the loaded Berger’s in a semi auto. They are absolutely the best factory load I’ve ever shot in a bolt gun.
 
I have a sig716 dmr2 in 6.5 with an 18in barrel.
I tested a whole bunch of factory match ammo and actually found it liked the sig 140 match round the best.

I would get a couple boxes of a few different ones and see what feeds and shoots well.
