There are a lot of opinions on this matter, its pretty impressive... If you are loading light I like the idea of a HOT 357 on the last round, seems to be a solid idea...
Keep in mind 38s can go from mild to wild, there are 1300fps 500 ft lb loads out there and there are 800fps 200ft lb loads out there, so it is a pretty versatile round, its what makes a 357 revolver so nice you can get ammo at 800fps and in the same gun shoot ammo that is 1800fps!!!
Also the reason I always tell people buy a few boxes of ammo with your new gun, 3 or 4 different kinds and shoot a few of them all find out what works for you, what you can control and follow up with is more important that what will kill a bull {unless you are hunting bull, then make sure you get a hot round}...
Your gun will also have a lot to do with your ammo decision, barrel twist and length can dictate your projectile weight, I have a sw 327 it shoots different amm than my vcomp, also the weight of the gun will dictate how well you control powerful ammo, My 686 competitor is weighted and a pretty heavy gun, I can shoot hot underwood rounds all day with it, but my 360pd weighs 11 ounces and shooting hot ammo out of it beats me up, I like to use mild 38sp with that gun...
Everyone is going to have a different need and want, no matter what fuels it, whether you are the guy that wants a cannon loaded with the biggest ball it will take or the guy that wants to be precise, in control, and accurate with something that will still get the job done, its your decision and there is no wrong answer... Well OK there are some wrong answers, like 500mag for crow control could be wrong, although I want to see the first shot...
