can you use 357 dies to reload 38sp in 38sp brass? also, does the brass make a difference, i.e., is the brass interchangeable?

Yes you can. Usually the dies are labelled .357 max/.357/.38 spcl. You can load a .357 casing down to .38 spcl pressures but it is unwise to load a .38 spcl casing up to .357 pressures. The reason being that even though you can shoot them through a .357, if someone was to put one in a .38 special and touch it off there is a good chance that someone is gonna get hurt.

NO, you can't, unless the dies are specifacally marked as such..

Some companys dies may be, but not all of them.

You can always load .357 with .38 Spl dies though.

The problem with the other way around is on some brands, the seater / crimp die will not allow the shorter .38 case to reach the crimp portion of the .357 die.

What you want to get is .38 Spl dies, unless they are marked as .38/.357, and then you can load everything by just makeing a simple die adjustment.

"...marked as .38/.357...a simple die adjustment..." Those usually come with a spacer. No die adjustment, other than the seating plug is required.

If you can adjust the internal plugs, then yes. Most 38/357 dies come with a spacer that is the thickness of the length difference of the two cases, making it easy

Mine did not come with spacers (I don't know any that do), but Redding makes a set (http://www.midwayusa.com/viewproduct/?productnumber=189290). I used them for years until I finally bought a second set of dies. One for .44 Spl/.44 Mag, one for .38 Spl/.357 Mag, and one "no crimp" spacer.

If you buy .38 Special dies, you can definately use them on .357 Magnums. They might even be labeled for both.

The older RCBS dies came with a spacer for their 38/357 dies. It just looked like a big fat washer. I still have one and it only works if you are using the same exact bullet in your 38's and 357's. :)

Thank you all. I'm not doing the reloading. Will forward to the person who will be doing the reloading for me. Now I'm off to Sturgis for the week for a little R&R. Any other input is welcomed and appreciated.

I have 2 sets of dies for the 38/357, one with do both the .38 Special and .357 Magnum and one is specifically for the .357 Magnum and are too long for loading .38 Special ammo. Like said above, they are marked...
