[QUOTE="Idaho Trecker, post: 3072581, member: 67706"] I'd look at 338 rum data for the 230 and take 10% off a mid load since the 33 sm is 10-11 grains less capacity than the rum which happens to be 10% between them. Might want to move to a slightly faster powder possibly. Or you can get the nosler data for the 225 ab for the 33 nosler and pick a mid load with that. The capacity difference between these two is 4-5 grains (more for sm when formed) which may be a better place to start than down loading rum data. [/QUOTE]
