I have not tried the 38 super. But I do reload the 356TSW which is one of the hottest little similar size rounds around. I use the 9mm dies and follow spec that were passed on to me by individuals that shot that round in competition years ago.
Follow the Lyman manual and check out the others too of the best loads. Lyman will always give you the accruacy loads and the hot loads! I think you will find it an easy round to reload.
Should be similar to the 9mm too and thats an easy one to load. I use the Dillon 550 and have all the dies preset for each cartridge.
Thank's sig. I have two 550 Dillons that I use to reload with. I'll order a Delux Conversion Kit for the 38 Super round on Monday. I like having everything set & just changing the tool head. I have a couple of loads in mind, but I like to hear what other's use.
