Home Forums Reloading Big Game Rifles 7mm Rem Mag; Retumbo vs. Rl22

These loads/velocities are an average of 5 shots from my Remington 700CDL 7mm Rem Mag 26" barrel.

150gn Swift Scirocco

71.5gns H1000..........3032 fps
67.0gns RL 22..........2979 fps
72.0gns Retumbo........3051 fps

154gn Hornady Interlock

71.5gns RL 25..........3076 fps
72.0gns Retumbo........3051 fps


150gn Sierra BT Spitzer

71.5gns RL25...........3098 fps
71.5gns Retumbo........2969 fps


I've tested and chronographed many other powders including H4350,H2213sc,RL19 and W780 and from what I could see RL25 followed by Retumbo were the best two powders for 150gn & 154gn bullets in my 7mm RM.
