I bought some Reloader 16 and checking the Alliant site I saw no data yet for 308 using any bullet but in particular the 150gr I wanted to try. I emailed Alliant and the guy mailed back they have not tested it on 308 yet. ? One of the most popular calibers in the US? Anyways, there is data on the 7mm-08 for 140gr.
Place to start using 7mm-08 data on the low end minus 10%?
