Just curious. I have a 14-15" 5.56 with 1:10 that works well with all but the heaviest (70 gr) bullets.

No idea, its what sig runs. My guess is you're correct. Small barrel needs at least one full twist and with the popular 62gr green tip everyone seems to be going lower/faster. I reload hornady match 68gr and 75gr and keep lots of green tip on hand. 55gr I just don't think has the kinetic energy so I'm glad for the 1:7 and heavy rounds.

Next gun will be a 300 blackout for all the split case necks I have.
