Looking to build a TC Encore 308 and trying to justify custom MGM or Bullberry barrel vs a factory barrel. lookin for input. No plans for shots beyond 300 and no plan to match shoot. If I go with the factory barrel plan to have it cut and recrowned @ 22". Otherwise would order the custom barrel at 22". One other question for Encore guys, will their factory barrels shoot 7.62 ammo w no issues?
