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
