I am using a new Accurate molds 140 and 147Gr boolits. Came out about the right weight but .359/.360.
Cut them down to .357 with minimal distortion.

You can size them a heck of a lot more than that, though if you get too carried away you start to have issues with your grooves getting wiped away. I have made hundreds of 358-429's into .350 boollits for low powered .348 winchesters. I fill the lube grove first and size to .358 and then run them through a .355 sizer, then the .350. Though I could probably dispense with the .355, if I didn't use it for this purpose, I'd never use it.

How do they shoot? My consistently most accurate 9MM/38/357 boolit is a Lyman/Ideal 358242 (120 gr) that drops at .362.
All you gotta do is fit the bullets to the barrel. If your barrel slugs out at .355" or .356", then .357 should work well...

In my experience, is a rare 9mm barrel that slugs .355. I have asked cast boolit shooter over the years. .356+ is common.
I run mine at .358 and would LOVE a mold that dropped at .359-.360.

My lee 358-125 RF drops .360 and I size it .357 for my 9's and .359 for my 38's. Works fine.

Yep.
I worked up a load. That boolit sits deeper in the 9mm case than the 125 gr. 9mm boolit. Work up carefully.
