.300 H&H Ackley Improved Data

I recently purchased a Model 70 in 300 H&H at Cabelas. When I took the 300 H&H to the range, I found out that it was really a 300 H&H Ackley Improved 40 Degree. What a surprise! Does anyone have load data for this caliber, COL, trim length. I have looked on the web and my reloading/reference manuals, Nosler, Barnes, Speer, Cartriges of the World., and could not find any load data.
