Based on your earlier post, I have to ask if there are other cartridges which you may eventually load for? The reason I ask this is to try to avoid purchasing extra powders. If you can use one or two powders for those cartridges, you're cutting down on expenses. As an example, and I'm sure there will be differing opinions, but I use IMR 3031 in the 7.5x55, 30-06, 223 Rem & 222 Rem. So, to answer your question with a question...
