I loaded up some with N560 and H1000.

H1000 for me. 58.5 grains if I’m remembering correctly. Shoots fantastic.

The data provided seems to have some pretty stout max charges. Work up for sure! I’ve only used RL23 and RL26 with 280AI and 175’s.
With the powders you have, I would try N560, 7828SSC, H1000, or RS magnum first and in that order.

7828 is what I use for 180 eldm. 58gr gives me 2850fps

I shot the top group with H4831sc and Berger 175gr Elite Hunter. And the bottom group with RL19 and a 162gr eld x. Top group was 4 shot. Bottom was 3 shot. 2940 fps on the 175gr grain.

If you don’t have pressure signs, and if the ES was low, I think you found your load.

I thought my max was 59.5 H4831sc with a 175gr. I went up to 60 gr and shot that group . It was 93 out. But my max is 58.5. So I'm 1.5 grains over max. No issue no heavy bolt lift. Or any marks on brass. I guess I will rework the load. And drop down to 56 work up to 58.5 grains.
