First, I'd like recommendation from users of LRP in 260 Rem. With 8" twist, I assume that you would most likely use 140gr bullets. Do you find the short neck that restricting? Is 260 Rem really giving anything to the 6.5 super LR? Secondly, if your 260 Rem barrel is shot out, would your rebarrel, or turn barrel and rechamber to 6.5 super LR?
What are the pros and cons of 260 Rem vs 6.5 super LR? Let's keep it practical, and not minute factors. I'm more into the KISS principle.
