I'd like to work a load for my 7 SS, using 175 bergers, out of my 20 inch barrel, seated at 2.950. I have an accurate load with RL 26, unfortunately found out the hard way that Texas heat and RL 26 don't mix well together . Any experience with Retumbo or N568? I have some data from H1000. I can get some N565 just not sure how temperature stable it is.
Thanks
