No .30 cal experience, but Noveske 556 barrels are better than LW in my relatively limited experience. Couple Noveske uppers and couple uppers with LW barrels - Noveske's shot better set up the same.

Thanks. What do you think the difference is? Overall rifle quality? Chamber? Bolt? Trigger? Actual barrel quality?
I haven't found the Noveske to be any better of a shooter than a LW (both in 5.56), but the Noveske barrels have the reputation for standing up to HARD use. Not sure if that's a factor for you, since most precision shooting doesn't typically see abuse.
