Just found this thread. So coming to the party a little late.
I know I am new, but I have been pretty Buisy with .357-38 special these last couple years.
I have shot every kind of lead from 30/1 to Lyman #2 thru my .357. Using different lubes, XLox, Bll, pan lube, powder coat.
I have yet to have experience leading. Accept for two instances.
1: I sized it too small.
2: I used Lyman #2 in the pistol.
As far as expansion my knowledge is limited .... But for a non hollow point bullet, I have found a Kieth style bullet expands pretty well in .357 with pretty much anything softer.then hard cast.
My current pistol alloy is basically hard cast mixed 50/50 with 30 to 1. Works in just about anything .35ish with under a 8 inch barrel.
I love the ..35 calibers, especially .357.
Because there's a lot of combinations that work well. As long as you do not run it too hard or size too small. You could basically pick up any chunk of lead you can mark with your fingernail. Make bullets, lube them with anything slightly slippery, and make that work IF NOT WORK WELL, 90 % of the time.
Plus revolvers just have that nastalgia presence, that just makes them fun to shoot and load for.
Ps.
@glassparman nice wheel gun by the way.
