A lot of people will try to free-recoil them, and groups will be all over the place. Your barrel may be ok, and you just need more technique to get it to shoot. Use a rear bag and a heavy bag that compresses against the sides of the handguard so the gun can't move much at all. Use a good trigger like a Geissele, AA, or Hyper-Fire. Dry fire until your reticle doesn't move outside of an inch at 100yds. I work hard to settle the gun before I break a shot, so it's like setting in a mortar base plate. I don't want the first or any follow-on shot to disrupt the position, so I troubleshoot it with small movements that settle the reticle into the center of the aiming point.
.308's are generally hard to tame in this regard.
