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.
