I got my S&W 586 back out recently (after a long retirement) and have been loading mostly 158 Missouri swc and stiff loads of 2400 and having a blast.
I Googled your 358429, and it looks good bullet, an Elmer Keith design, 173gr. with a big flat nose. Do you cast them yourself?
I reloaded for the first time ever today in Andrew's class!
45 ACP.
