Thinking about using this for the 308 with 110 Hornady flat bases as its currently a (Very) compressed load in some brass like the Outback Factory OSA brass that holds less than normal and struggles with a full load. Will need to dial back a bit too by the looks.

CD.

This was pulling projectiles from 308 super performance factory ammo for 308 with 150 grainers, was more grey and smaller ball style than both 2206h or super performance in the reloader line. So I think Gregs smack on the money there... lots of different 'superperformance' brews that the one the reloader can buy....
