Hello
I had a pleasant surprise last weekend with the LEE 358-158-SWC.

Here’s how it looks loaded. On the right;

I did some shooting with it last year using AA#9 and 2400;

The alloy is WW with 5% tin. Sized through a .358 H&I die to crimp the gas check on and then tumbled in Alox. They weigh out at 159-160grs. They are intended as plinkers.
So, a few weeks ago I got a whim to try a powder that I’ve been working with in 10mm.. N-105.
Vihtavuori, in their .357 Mag data, says 12.6grs of N-105 is max for a 158gr jacketed bullet. So I dropped down a grain to 11.5grs loaded five rounds and shot them in the 6” Taurus. I was using a Caldwell pistol rest. Cases fell out when ejecting.
Data taken with an Oehler Mod 33 chronograph
Data on target; FPS average, velocity spread, standard deviation and temp F°
All the target circles are 5½".

This is worth looking further..
I know this powder isn’t one that is sitting on a lot of benches, but should it become more available again, or you know someone who has some, it might be worth a try.
