LOL! No true handloader uses up a can of powder before buying another type! That's why we all have a dozen or so cans of various stuff sitting on our shelves. In fact, you should immediately run out and buy 3 or 4 more types before proceeding. Besides, testing multiple powders and multiple loads gives you a great excuse to spend more time at the range. You should probably pick up a few more bullet types while you're there to.I Dares I Wins said:Fluffy, that's exactly what I went with, 58grn of H4350. I'm going to use up this pound of powder then switch to a slower powder as instructed. Thank you all for your help.
