Im currently running an 18" barrel and debating on moving up to a 22"/24" barrel. I initially went with 18" because i wasnt interested in having a grossly long barrel. I previously shot 308 in 16" and 18" gas guns so naturally this is what i went with. However, i just recently picked up a 22" 6.5 creedmoor and love it.

Im looking to increase velocity a bit and also want a submoa non factory barrel. Im holding 1moa or less on average with a factory prefit. Anyone else move to a longer barrel after awhile? Ive had it for about 3 years now.
