Hi Team - I'm dusting off my Sako 85 7 Rem Mag & want to put together some varmint loads. The speer TNT's would work well but have the BC of a trash bin so were looking at the 120gr Vmax with a stiff load of perhaps RL22. Other choice is maybe something in the 139/140gr range like an SST or ballistic tip. Any other projectiles I should be considering here? Is there a powder of choice to push these lightweights at warp speed for maximum mist effect?
