Batch to batch all this can vary up or down by 5-10%. You can see Accurate Magpro and RL26 are closest in burn rate to Retumbo. But Magpro may not be temp stable, and RL26 may be but with exceptions over 95 degrees. N565 may be a good substitute as it is supposed to be temp stable. The new N568 is also temp stable and is in the right ball park. But here is all the hard data to consider. You can get some extra velocity a lower pressure most likely with the slower powders, especially with larger heavier bullets. So, if you were shooting RL33, N570 or 8133, you can get to some higher velocities vs Accurate Magpro. with lower pressure. Even moreso for RS Magnum. [/QUOTE]
