I have been using Herco/Unique in my 300 Savage... same basic case as 308. Using both the 185/155 leads... it has been a pretty balanced load. I am riding that broke collar bone on right side. 1 standard 3006 round and it goes pop. I tend to load WAY back on my rounds, start 50% and go up till I am happy with what I have ... normally 60-75% posted load. For non-automatic weapons it works, makes shooting with grand kids easier as well.
