7mm-300 weatherby - 01/24/23
I've aquired a 7-300 weatherby 9tw and fire formed some brass with 180 hornady and magpro from 74-78 gr with no signs of pressure.
I'm looking for load data for this case and bullet. I have magpro, 7828, h1000, h4831, rl22, rl26 and imr 4831 to work with. The gun shot magpro well enough but I don't have a lot of experience in temp swings with it. I don't mind burning the h1000 up if it is the right choice.
Anyone have any recipes to share or ql data?
Thanks in advance.
