Thinking of re-barreling my 6mm Rem in a Rem 600. I have heard the 6.5x47 is able to reach similar velocities to the 260 Rem. It would allow long bullets to be seated out like the 130 grain VLD Bergers. That appeals to me. How much more poop in a 260AI? So for a 5.5 pound rifle for sheep to caribou with a featherweight 22" barrel 260 Rem, 260AI or 6.5X47 and why? Guide me Oh wise ones!
