My cousin has worked with RL17 pretty extensively. He has said that the charge weight, bullet weight, and rifle make a difference in the powder stability. He noticed that in the 6.5x47 Lapua 17 was one temp variance. Then in his 300wsm the temp variance changed when shooting Berger 168 Hybrids...
This shot in a 30” barrel using RL22. 6.5 Creedmoor shooting 147 ELD-M’s.
I wanted to go higher, but I was getting a stiff bolt lift at 45.6 and 45.8. Book max on Sierra load data for the 150 is 46.2. It’s weird because a max charge for RL19 is 46.4. I thought RL22 was a slower powder.
