What velocity are you wanting to hit? I have the ladder graph using Hornady 9x fired brass trimmed to 1.510" that I did back when we were first talking about using Precision in the Grendel if you think it would help you. The only thing is I stopped at 27.9gr because I had a primer with a large black ring around it so I quit the ladder at that point. I think that the primer pocket was wore out and not the load doing it. I did the ladder with my Howa 20".
