Well, my greed and petulance is coming out.
I always want as much accuracy as possible. However, one of the reasons for building a 308 in the first place is to be able to use military ammunition. (Because anything a 308 can do, an '06 can do better.) so.... I am probably trying to have my cake and eat it too.
Just an FYI, I have an email to Pacific Tools pending. If they respond I will post the results here.
