Could someone point me to a source for which powders are used for 9mm, 40, 45 and 38spl.
It's really more like #7-52 on that chart, minus the powders that are labeled as shotgun only powders (20 and 51 mainly, but a couple others are hard to find data for).Not all are optimal but #13 thru #50 ish on this burn rate chart.
