I also use the 165 grain in my 308, thats all we have ever used inour guns were 165s. They get the job done right away.

I shoot the 165gr fusions in my .308. I am very pleased. Last year I shot a buck from 16 yds with incredible expansion. The chest cavity looked like a bowl of melted jello. bang, flop. By the way, the .308 with fusions is my only rifle, I don't reload for.
I really like the 100 gr sierra gamekings in my .243 for deer.
