A couple of .357 loads that I like:
- 158 grain cast bullet + 8.0 grains of Herco.
- 148 grain cast wadcutter + 4.5 grains of Red Dot.
- If I want something more powerful than the Herco load, I use AA#7 powder but I don't remember how much; about 10 or 11 grains. I don't shoot those very often.
- And if that's still not juicy enough, I switch to a .41 Mag or a .45 Colt.
I've also shot some 125 grain JHP's using 9.5 grains of WSF, and that was a good load except I don't really like shooting j-bullets.
