I bit the bullet and bought 8lbs of RL 23 this week. So I am invested. I saw a lot of posts on multiple forums where guys love it in a 7 SAUM. I see others will use it in a 6.5 PRC. If you use it in either let me know what you learned, please. I have loads worked up for both calibers, but I really enjoy tinkering with new load development. It is kind of my happy place.
