There is only one .280 out there right now and it has been at the smiths for too long! Another story. Not much data on this one yet, but it would likely have less gain than the other Sherman cases comparitively because the .280 A.I. is already based on a longer case. The Sherman has a longer body with less taper than the A.I. I would guess no more than 50' gain......Rich
