Ramshot has some load data for lead in a .357 SIG.

I shoot the Accurate 35-125YG in my glock (with KKM barrel) and with a full case of AA#9, I'm sending those pills in the 1400 fps range.
I also use this same boolit in my 350 legend and am sending it in the 2500 fps range under a solid charge of W296...

The .357 SIG seems like it should use PC boolits instead of lubed. The lube groove can take up a lot of the neck length, if you happen to be able to keep the lube groove out of the powder (is that critical though?). I’m tinkering with lubed boolits, and I’ve used the 125 grain bullet from Hunter’s Supply with good results... but I still suspect that PC will ultimately be my choice here.
Did you guys see the other post, that LEE dropped a new 356-147-TC mold?
Just because it’s a bad idea…
…. Doesn’t mean it won’t be a good time !
