I was having some fun trying to work up the best load for my .308 and kept coming back to 165 (168) pointed boat tail at around 2700 fps.
I eventually called steyr looking for a trigger recommendation and asked about their recommendation on ammo for accuracy. They said they had the best results using 167grn pointed boat tail at around 2750 fps.
My point is, sometimes it just works and much of the dialog is trying to explain why.
