.300 Norma Hornady 250 grain A tip load data.

[mjsand44]

I'm building a .300 Norma on a Defiance action and a bartline 1-8 3/4 to 8 gain twist. It will be finished at 30 inches. I have N 570 powder and plan on running the Hornady 250 grain A-tip. I can't seem to find much for load data and was looking for some help on where to start. The Vihtavuori website only goes to the 230 burgers and the Hornady site only has data for the .300 PRC.
Thanks

From similar work with GRT I’d say loads in the mid to high 60s are pretty common on this board. Like driving drunk or crossing the street without looking, it works fine…most of the time.

I start my loads about 5% below the "Near Maximum" number, and work up from there looking for pressure signs. So far, I haven't been run over by a bus.
