[QUOTE="RDM416, post: 459755, member: 3745"] lovedasnow, I have been shooting 338/378s and 338/378 improved (338 Kubla Khan) for several years and have tried a lot powders. For best velocities I keep coming back to RL 25, although it is not the best for temperature stability. I have done qute a bit of temp testing and it is fairly easy to compensate for in typical conditions. I am currently working on some loads with Retumbo and have drawn no absolute conclusions yet, but it looks like RL 25 will win in the velocity race. In my experience US869 and H50BMG are too slow. I have a 30" barrel on one of my Khan's, but still have not been able to get these real slow burning powders to even come close to the same velocities as RL 25 or Retumbo. [/QUOTE]
