Got a 7mm Mag from a member on here recently. Going to play with the 195's. What powder's work for them in the caliber. I have N570, N565, RL 26, H1000, RL33. I really need Retumbo. And I need what your end result with these were as far as your load data. The barrel is. a 24" Proof 1:8. Top 3 folks that help the most there's something in it for ya.
