I am just thinking Lee's statement should maybe be clarified a little bit.
He is correct and has shown that the pressure rise in BH is slower than T7 and at any given time BH does not produce as much pressure as does T7, but because of its 'progressive' burning nature it DOES produce a greater 'total pressure' which with heavier bullets will normally produce more velocity.
The heavier the bullet the more efficient BH burns.
No matter BH is a very good powder and serves a lot of people very well, but as I have always said it is not everybodies answer.
