I know I want a switch barrel rig, now I need to make up my mind on caliber. I want a short 20" in. 308. I just can't make up my mind on a longer 26or28"barrel caliber. 308 would make it simpler, yes, but the 6.5x47 lapua sure looks nice. Barrel life is pretty good, accuracy is what I am looking for, and long range performance is promising. So do I get a .308 and 6.5, or just stick with. 308? Any input?
