Actually, I have some in my box and some 78 gr. vials of that powder. (we are going to the range tomorrow since rain is forecast for Tuesday) If I can remember, I will pop one and give you an "actual?" My Brux is also 27"

My Brux is 27" as well. With the 275MH and 78 grains of of 4198 I averaged 3050 fps.,so I would say that Jeff is right on with 3100 or so.
