Gunsmithing 280 AI barrel length?

[huntersedge89]

What is the shortest that you guys would recommend going on a 280 AI build, to be used with a suppressor, without sacrificing too much velocity?

Anyone have a 280 AI with a barrel around 22"?

Pushes the 162 at 3000fps.

25" for mine. Still easily gets 162 amaxs to 3000. 180s to 2900. Safe loads suppressed.
