It seems that Larue went with a rather rare 1:8 twist for their 308 uppers, unlike the more common 1:10 twist. While googling, I get a lot of 300 blackout results (not what I'm looking for). I do reload and plan to reload for this, but I'm saving for an optic right now. I believe the 1:8 twist is better for heavier/longer bullets, but I need to be mindful of magazine OAL restrictions. In the meantime, I was curious what others who own this same upper seem to like for accurate store bought target ammo and deer hunting ammo.

My 2 Larue 308s bought a while ago are both 1 in 10 twist. When did that change?
No idea. I didn't know they had a 1:10 before.
Pardon my ignorance, but what does "FGMM" mean?
I remember them telling me it was 1:10 back in 2015. However, there is no information on the invoice.
There is no information on their website other than for the Siete rifle barrels shown as a 1:8 twist.
I use those primers for my 223 reloads. I didn't realize they made complete ammo too. Thanks.
It's kind of a gold standard for 308win, I can't remember how many times I've heard and read if a 308win rifle doesn't shoot it well there is something wrong with the rifle.
What model larue did you buy? The upper or a whole rifle?
I know a 1-8” twist .308 win barrel will shoot 168gr ELDM like nobodies business, or at least mine will. You couldn’t shoot a 155gr bullet out of a 1-8” 308 fast enough to cause issues.
