[QUOTE="liltank, post: 1426421, member: 13275"] 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. I was having trouble finding stability in my SD’s with faster powders. I was using 4451. The lowest SD’s I could get were low teens. This is using the magneto speed. I do currently have a load with RL19 that has an SD of 8. Two groups printed a 5 shot group of 1.8” and a 3 shot group of 1.7” at 500yds. Velocity is 2842. I wouldn’t mess with it, but according to the Hornady 4DOF, RL22 has a better temp stability compared to RL19. Therefore I thought about trying 22. Normally I do the OCW test. Thought I would try the ladder after watching a test done by the 65 Guys. [/QUOTE]
