6.5 Creedmoor Brass - AR10.

[dug]

Gas guns are tough on brass for sure , that being said , it depends how you handload your ammo.
I have run both srp and lrp brass lapua lrp and peterson srp to be exact .
the premium brass last longer in a gasser ,period
srp brass hold primer pockets tighter longer , but there is a .3 grain reduction in powder charge between the lapua lrp and peterson srp brass to acheive same accuracy grps
i have not done a water volume test between the two.
this info is related to the 260 rem gas gun not the 6.5 creed
im old , i have been shooting the 260 before it was marketed a remington cal. My first set of dies were custom made and labeled 6.5-08

Here's a good comparison.


I guess from everything I've heard and read, I'm leaning toward the small primer pocket.

At least you can find small rifle primers these days. Haven't seen a large rifle primer at my lgs in over a year.

Don't waste your money on premium brass, I was able to produce many 1/2" - 5 shot groups shooting an AR10 I built. Everything is magnified with an AR platform due to many things including but not limited to position behind the platform, Repeatable Butt Stock Placement, Breathing, Trigger squeeze, etc. Work on your fundamentals. And one last thing practice, practice, practice...
