Re: LWRC Aftermarket barrels in 308
I looked for an aftermarket barrel as well, but soon learned the interference fit meant only LWRC could supply the barrel.
Try Federal Gold Medal Match 175's or Black Hills Match 175's. This was the best performing factory ammo in my 20" 1:10 twist REPR. My REPR does shoot in the .75 to 1 MOA range with this ammo. My 1:10 twist barrel does not like the lighter bullets. If you happen to have the 1:11.25 twist barrel you may have luck with the lighter bullets.
