I am trying to work up a load with retumbo and was curious if anone else loads the 338 rum with retumbo?

I've reloaded the 338 rum but not with retumbo. I think it should produce decent velocities with a 225 or heavier bullet. i shoot a 215 gr sierra with a good dose of rl22 behind it...works great...shoots in the .3's. as for the retumbo looks like you want to start (with a 250 gr bullet) at about 95-96 grs and up to about 101 or so at the max.

hope this is helpful.
