Thanks.
I just loaded powder ladder and group size checks with RL-15.
I have most of the powders listed on hand and am seeking velocity as well as group size...
The HO #2279 75 Gr. BTHP has a lot of data in several manuals...and is grouped with the 75 Gr. A-Max in the Hornady manual with the same charges weights..
I'll run the programs to see what a drop of 0.040 in B.C. means.
Thanks, BarryC and Seafire.
