Thinking about buying a 1-6 or 1-8 for one of my AR's and shooting a pig with the 64 gr Nosler Bonded, the only Barnes' I have loaded are 55 gr TSX's, bet they'd work too, but, also bet the Nosler would have a heavier splat penetrating punch than the buzzsaw Barnes.
1x7 or 1x8. I don't think you want a 6, they are specialized, though my 6.5s shoot 52s just fine amazingly...
