[QUOTE="Engineering101, post: 984257, member: 63138"] As was mentioned the new velocity king in the 300 RUM seems to be RL-33. I'm running the 210 Bergers with 97.0 grains at 3,040 fps (that is where it is accurate) and it is just loafing along. I'll probably get 10 reloads out of the brass. Shot a 0.500" group at 200 yards too so it has accuracy potential as well. I have noticed moderate temp sensitivity though not as bad as RL-22 or RL-25 which use a different technology and are really bad - unusable if temp is a concern. Per test data on Barnes's website H1000 and Magnum were very stable over temp. I'm guessing Retumbo would be too. If temp is concern those are three good powders. My go to load in the 338 RUM uses Magnum. I've done the frozen ammo test on that rifle and it was rock solid. No drift at all. Now if I could just find some more to buy. [/QUOTE]
