Did you chrono that load? looks similar to what I got with TB.
BTW - found a guy selling a 5lbs jug of TB about a month ago - I'm pretty set for a while. I did notice that the jug was the same size as a 8lbs jug of regular powder, so that shows you how bulky TB really is.
Just for grins, I have a cast bullet load for my 375 H&H with TB. 265gr GCFN @ 1500fps - really makes practice fun!
