I would certainly second what Ray has posted... I know what T7-3f will do without a wad and BH is physically builds more heat than does T7.
And I think it has already been mentioned but because of BH's progressive burning capabilities and the weight of the projectile you are proposing - reducing the powder weight is the prudent thing to do.
Do you have a chrono?
