I acquired a savage large shank barrel in 6.5 Creedmoor with the full intentions of re-barreling my Savage 110 PCS in .223. After shooting that one more though I'm kinda starting to like it. I'm thinking now I will pick up an undesignated Savage Target action for this Creedmoor barrel. My question is, if you were going to build a 6.5 today, how short would you go on the barrel? I initially thought 14-15", but here in East TN I rarely have the chance to shoot more than 400 yards and honestly hunting the fields one doesn't get much more than 250 yards. Just curious on your guys thoughts...I see AR10 pistols in .308 and 6.5 in the 12.5" length, and since I have absolutely zero experience with them I don't how they behave or perform.
