With 158's, you might want to consider "medium" speed powders. The two I use is HS-6 and AA5. They bear no resemblance to each-other.

HS-6 is great powder but it needs to be loaded up higher in the pressure range, or it burns dirty. Real dirty. I use it for 45 ACP a lot for high-performance rounds, but it took some time tweaking the recipes to get the loads to burn clean. But those clean loads also yield some rockin' rounds.

AA5 is much cleaner and versatile. And since you're loading 357, if you find some, grab it. Good stuff. You can load lead 158's as (realistically) hot as you'll ever need them. Meters really well too - second only to it's faster brother, AA2.
