I have decided I am going to re chamber my 6.5CM to a 260 AI the barrel is young and lapua brass is much cheaper I’ve been noticing for 260. The 260 AI seems to be around 60-100 FPS faster than my creedmoor from a 22 inch barrel vs my 26 inch barrel running H4350 and N160 both we have much better accuracy with heavy bullets using N160 in both my 6.5 and his 260AI
