    Decided to try out Frank's advice from one of the podcasts and go with a 22" barrel for my AXMC in 6.5 Creedmoor. Wondering what kind of speeds I can expect to see with 130 and 140 class bullets out of it?
     
    My 24" 6.5 creedmoor shoots a 140 Berger Hybrid at 2830 fps. 2850 fps with a suppressor. 42.5 H4350, Lapua brass, CCI BR4 primers.

    It all depends on your barrel and powder lots. Could be fast, could be slow. On the faster side, I would expect 2780-2800 fps. Slower side could be around ~2720 fps.

    The velocity node will ultimately dictate where you end up speed wise. Unless you throw caution to the wind and just chase speed, but I would recommend finding a consistent load over a fast one. After all, it's not a race.
     
    I have a 22" Bartlein M24 profile on my 6.5 Creedmoor. I chose to go with 22" so that when I attach my Ultra7 suppressor it isn't super long and difficult to maneuver. Weight wise I'm not sure it saves me much with the heavy barrel profile. I am getting 2760 fps with 42.0 gr H4350 behind 140gr SMK.
     
    I get 2690 with 143 out of a 19 inch 6.5 cm but I definitely would never choose to use it in a competition environment because my 27” is shooting so much faster. Military environment is a different story.
