All-

Trying to make chicken soup out of chicken poop for a buddy....

Got a 300 Norma Mag rifle, H1000, RL26, N570 and Retumbo to work with.

Only bullets I got are 220 ELD-X

Can’t find any load data for this, could use a starting point.

Much appreciated-

This should get you close. You could probably drop the min down a grain or 2 for starting. I don’t have anything in my Lee, Nosler or Speer manuals.

N570 start around 84 and go up to pressure just got my 245s flying good this week with 570. 300 Norma and that powder were made for each other….
