Here is the load data I used for the Sierra 160s
https://sierrabulletsblog.com/2018/03/06/sierra-bullets-7mm-remington-magnum-load-data/I am open to other powders and might try different powder before settling in. I am curious about trying Retumbo at some point. I am starting with this powder because a lot of people here have told me that its an all around good powder for multiple calibers.
I loaded so many just in case I had a bad three round group i could let it cool off and try again. Of course if one load doesn't work well after six shots then I would stop shooting that load and move on. I can always pull the bullet and save the powder. Also I am using my neighbors reloading equipment and the range is about 45 mins away from my house. My mind set was to have more than I needed.
