I'm about to order some 6.5 CM ammo and would like to know what I should order. It's a new rifle so I don't know what it likes yet. However, I’d like to know from other CM shooters what your gun likes. I’m considering 120 GRN or 140 GRN Horneday. The barrel is a 24” MTU Krieger with a 1-8 twist. What do you think I should start with?
