I'll have my custom 6.5 Creedmoor in next week. It was built by Mark at SAC. The barrel is a Bartlein M40 1/8 twist 24". I'm looking to shoot the factory Hornady AMAX 140s initially, until I start reloading. It seems like the 140s are preferred in most cases for the 6.5 CM. For you 6.5 CM owners, what's your thoughts/recommendations? Also, I'd like to start using my Ballistic FTE phone app, but should I chrono my rifle first or just use the factory muzzle velocity of 2710 fps? Thanks gents.
