Thanks for the link,
I was hoping 570 would work for the heavier 200 class bullets in the 300. I just have to do some test to see what happens with that.
I did load some in the 7mm RM, 175 GK's , it produced 3,030 mv and moa. That can be tweaked.
Wanted to try some 7mm 180 ELD-m but the bullet seems a little long for my CLR, it seems to have a shorter throat for that long bullet.
