7mm Rem Mag load Help

[Stewart2550]

I am loading for 7MM Remington Mag for the first time. I have 165 Grain Sierra Game Changers and I have the Hornady and Nosler manuals that have close data but not in the 165. Looking for help with some good starting numbers using IMR 7828SSC but would be open to different powders like H1000, Retumbo, or RL25. Any guidance would be appreciated.

Some time back I got an app for Sierra that has load data. I think it was even free. 71.2 gr R 25 is their recommended accuracy load. 7828 62.5-67.7 H1000 61.1-70.8 R25 62,4-71.8
