I have had a Ruger GP100, .357 4" for over 20 years. It has handled every factory load and some hot hand loads (max load according to the powder mfg). No problems, ever.
Just remember that it takes a bit of effort to get the lead residue cleared out of the grooves. Even "hard cast" leaves lead behind. Brass brush and a good solvent will take care of it.
As for a hunting load, all I use for hunting loads, either 44mag or .357, is Hornady XTP's. In the case of the .357, I use the 158 gr XTP with H-110 as the powder. But then I build all my own hunting loads.
JMHO & YMMV.
