Looking for some load data for my 6.5prc 24" proof barrel 7.5 twist. 131gr hammer hunters, hornady brass. Anyone have a load worked up with retumbo? Also have N160
Retumbo for 131 hammer hunters data?

H1000 in store as well
I would probably start with the N160 powder. Vihtavuori lists data for the 6.5 PRC and 135 A-tip that would work as a starting point for the 131 Hammer. The three powders you listed are a little slower than ideal for that combo though.

I just did load development for a friends gun with the same components. Ended up at 60.7 grains of Retumbo. 20" barrel 2990 fps. Never found pressure with the ladder I shot. I think you will be at max case fill with the retumbo before you find pressure.
