I got this idea some time ago, and lets face it folks....those shot capsules just aren't always around. Not to mention the LGS told me those lighter revolvers (namely the 38Spl) have a tendency to have a bit more felt recoil and the shot capsules want to back out of the case.
I got in some 357Max brass, and I trimmed some down to 1.520 from the 1.600 factory 357Max length. For the 357Mag loads you can just leave it alone since the 1.600 length will work just fine.
I'm pretty much using regular loading data despite the fact I'm using more shot.
For these I'm using 4.5gr of B-Eye which in my revolver works just fine, and it's a 357Mag.
Once I prime I put the powder in and I'm using an aluminum 8mm (.323) as an over powder wad which works just fine. Factory shot load is 100gr using the shot capsules Speer makes when you can find them. These hold a bit more and I put in 120gr (20% increase) in these. The Speer ammo for 38Spl holds 100gr of #9 and I'm using #8 since that's the smallest I have right now, which is a 20% increase in payload.
Here's the Stats on the factor 38Spl shot shells. http://www.midwayusa.com/s?targetLocation=%2F_%2FN-21694%2B4294950935%3FNp%3D2%26Nr%3DAND%2528p_visib le%253A1%252Ccustomertypeid%253A1%2529%26Nrpp%3D24 %26Ns%3Dp_metric_sales_velocity%257C1%26Ntpc%3D1%2 6Ntpr%3D1&userItemsPerPage=48
Now what I use is something called a notching die, it comes from CH-4D and this is what it looks like. Granted the link takes you to the die but that 1 in particular is for a 50BMG but I didn't look around for the exact same thing I have although I know it's in there site (somewhere). 50 BMG Blank Crimp Die : CH4D

Now your going to need to reduce the diameter a bit so that it'll clear the forcing cone. For that I used a 22Rem Jet #1 form die, and I know not everyone has that. But I'm sure you folks have a LEE push through sizer in 356 which should work just fine.

From left to right: 357Mag with 135gr #8 shot....Speer capsules loaded in 38Spl.....38Spl made from 357Max with a 120gr load.
All but the Speer shot capsules will cycle in a lever gun.

I know it's hard to tell by the picture, but they do split after being 1x fired.
Want to prevent that?.....Just roll crimp the end just like jmorris did and the problem is solved.
