[QUOTE="Hand Skills, post: 1381749, member: 103303"] [ATTACH=full]87179[/ATTACH] I have a .308 BLR with 18.5" bbl. I get ~2600 with 165gr AB's Haven't shot anything past 300yd with it yet but my ballistic table suggests my loads should have adequate velocity for expansion to 500yd. The .308 is a very efficient cartridge. From what I understand, it only needs an 18" barrel for a complete burn with mid-hvy bullets. Here is some data on velocity vs bbl length. Seems to avg ~20fps/in [URL]https://rifleshooter.com/2014/12/308-winchester-7-62x51mm-nato-barrel-length-versus-velocity-28-to-16-5/[/URL] [/QUOTE]
