I will never be without one, or three, .308’s. I have several calibers in the safe, but love the .308. Shoot F/TR at 600 and 1000 with one, hunt with one on a regular basis. I have a 6.5x47 and love it. I would say build one, you won’t regret it. But I can’t bring myself to re-barrel a .308 to another caliber. Maybe it’s just me.
