Post #2 said it best.
I'd add that for a regular defense round just in the home, you may also want to consider a high quality frangible like Corbons popular Glaser Safety Slug(silver) or the powerful Magsafe .357 load. Some pre fragmented or "exotic" rounds like Extreme Shock USA or RCBD(Le Mas) are not like they claim but there are merits to using a frangible in home defense for Magnum revolvers.
Keep in mind the blast, recoil, muzzle flash, etc. The .357magnum is not for the timid,
