I used to use blue dot for all my 357 and 41 mag loads. Now Alliant says not to. I need a load using Herco for my model 58. I have seen a lot of people saying they use Herco for the 41 mag, and the older reloading manuals have it listed. Unfortunately I don't have any older reloading manuals. Anyway I was wondering if anyone has data for Herco using a cast 215gr SWC that they want to share? I am not able to find much on it.
Thanks
