I have a jug of WC 820 surplus powder I use to reload my 357 mag bullets. You can use H110 powder recipes, but back off about 10%. Anyone here ever use H110 or WC 820 to reload 38 Special? Need a recipe if you have one.

It is not a happy combination. WC820 need higher pressures to burn cleanly, maybe even to ignite properly. I have WC820 from 2 different production runs, One loads to H110 data and the other loads to AA#9 data, neither works at lower pressures. Try a faster burning powder. Good shooting!!!!!
