38 special loads in a 357 magnum?
First of all I have to say sorry. I know I could look this up my self but currently all my reloading books are boxed up... had a leaking pipe.
I have been thinking of reloading for some CAS fun. I know that you can load a 357 magnum brass with a 38 special load and have it fire, the question is what can I expect? Will the velocity be higher than the 38 special (with the very same load) or will it be lower or will it stay the same? I know this may be a dumb question but I am looking to reloading people with more experience than my self.

For some reason, I completely mis-interpreted the OP's question. Sorry about that. For an actual answer see 2 posts down.

The same powder charge in a larger capacity case (.357 vs .38 Spec.) will result in lower pressure/velocity...

Not a criticism, just an observation:
I'll bet there would have been less confusion if the subject of the post had said "357 magnum brass". The human brain has a really nasty habit of seeing what it expects to see even when the words are right in front of us. |

You can use 357 cases or 38 special cases in your 357. If you use a lot of 38 special cases you may get some lead buildup inside the chamber that has to be removed once in a while. You can also use light 357 loads.

I use Hodgdons CLAYS powder for low to intermediate loads in 357 brass.
3.4grs will get ya 850 fps or so 4.4grs will put ya close to 1000 fps CLAYS is a very dense powder , so I load in batches so I can inspect the powder levels very closely ,as 4.4grs will only fill the 357 case 1/2 way or there abouts . CLAYS will burn clean ,cleaner than other powders at low pressures & even cleaner as pressures go up. CLAYS is also the most position insensitive when loaded lite . Hodgdon sells it in 14oz & 4lb containers , mite sell it in 8lb ,but have never seen 1. If only limited to 2 revolver powders , it`d be CLAYS & H-110 or 2400 I use regular primers to lite it , did`nt see no difference in ES when using mag primers.

Believe it or not, the powder makers know all about CAS and make powders for just this purpose. They bulk up larger and fill your case to prevent great variation in ignition, but are at the same time very mild. Trailboss is one of these powders.

Take a look a Alliant's load page for CAS. I note that Alliant loads the .38 Special bullet with more powder and get more velocity than using the same bullet in the .357 magnum brass. Can anyone think why Alliant would limit the .357 loadings more than with the .38 Special ?

I load light .38 Spl type loads in .357 brass all the time. Like GP100man I use Clays for one of my favorites using a 125 Gr bullet. It is one of the least position sensitive powders at these power levels, burns clean and is accurate. A triple charge will fit in the case, so be on your toes while loading.
I like WST or Competition with plated 148 Gr HBWC's in .357 brass. I run them at 700 ish FPS. Nice accurate soft shooting load I can shoot all day. They are also fairly position insensitive at the levels, plus the WC fills much of the space in the case. Same caveat. You can double charge a case if not paying attention. When loading .38 Spl loads in .357 cases you may need to increase the charge .1 to .2 Grs of powder, but sometimes with very fast powders you will not find a need to do so. Quote:
