I am working on an AR10 platform build with the help of another Forum member here.
I want a 24 inch accuracy conscious barrel for this .308 build. I'm addicted to tight groups better than 1 MOA even for semi auto.
Up for consideration are either a Lilja bbl. 24 inch with 3 grooves or 3 lands of rifling in 1 to 11 twist or a Bartlein 24 inch with 5 R rifling or 5 grooves or lands with 1 to 10 twist.
I will likely use this platform on hogs and coyotes, and may use hammer bullets. I'm thinking 150-160 gr. bullets and below. But occasionally maybe 175 to 180s.
Do hammer bullets with their low engraving profile prefer more or less rifling grooves? One side of me says 5 sets will help stabilize them better than 3 but I have no experience with them, and just don't know the technical answer.
Which barrel would you get and why? I will have either fluted, and mount a muzzle brake on it.
Its all a DPMS pattern.
Opinions? Facts? Experience or actual data?
