I got some and used it in my .308 (26” No. 1) a few years ago. I shot one deer with it an, if I ever use it again, I will stay off the shoulder...what a bomb! By contrast, I shot a very similar buck, same distance, same hit the previous year with that rifle using my handload of 150 grain BT over Varget and it worked well without all the mess. I don’t believe I’ve ever seen a shoulder destroyed to the extent of that one shot with the Federal Blue Box. They did shoot very accurately in that rifle, however.
