well now let's see. first, let me point out that while i've shot both, i've never loaded either cartridge. i'm sure there are other more experienced people who actually know this stuff. nevertheless, it's a learning experience for me, let's proceed.
judging from my hornady 4th edition manual, they both use a variety of .357 or .358 bullets from 110 to 158 grains. i'm seeing 357 bullets going up to 180 grains.
then i'm seeing .38 velocities ranging from 700 to 1050 fps, 357 velocities run 850-1800 fps.

so my guess is that you could safely use ANY of the lighter 357 loads which yields velocities within the 38/357 intersection.
now, what powder do you want to use,? sr7625? green dot? win231? on and on....

yes, looks very doable to me.hopefully someone who knows this stuff will come along
never submit! (click "submit" button now.)

In general, you can put any published .38 Special load in a .357 Magnum case. Pressure & velocity will be a bit lower, though; for this reason, I'd shy away from the light .38 loads in .357 cases lest a bullet get stuck in the bore.

Also, there are some powders used for .357 which are not applicable to .38, as they can be erratic & show dangerously high pressure spikes when loaded below specific chamber pressures (which happen to be above max .38 Sp pressure). For this reason, if you find a powder listed for .357 but not for .38, don't try to extrapolate downwards - bad things can happen.

You'll likely get sooty cases with light loads, though, as the heavier construction .357 cases take more pressure to get the case to seal against the chamber wall; nothing to worry about, just clean the cases as normal.

I'll keep this in mind once I learn how to reload.
