I bought half a case of Bitterroot Valley .357 Magnum 158 GR Lead semiwadcutter. ITs lopping along at about 1000 fps.
Its a good shooting round that doesn't beat my hands up anymore. I would carry it as a defense round in a second. As a matter of fact, I bought it because I couldn't find the Remington of\r (I think) Whinchester version anymore. Those were going a little faster, but a solid SWC between 800-1100 FPS should serve you well.
