I think I got close to 80 fps faster with Lever than I did with TAC and 55 grain bullets. But I don't have my notes with me.

I did get a real boost in my 223AI and 55 grain bullets. In my 22" Montana barrel it was getting 35 something with no pressure signs. I sold the gun and gave the guy all the Lever I had (package deal) and just haven't had good reason to pick anymore up. But I might get another pound to try in my 204 Ruger and see if it does any better than TAC there. TAC has been real good there too with both accuracy and speed.
