Kalifornia passes "feel good" legislation hand over fist, legislation that is looking for a problem to solve and affecting only law abiding persons.
So, after 40 years of that nonsense, that's why I now live in Arizona.
You’ll need to get closer to .323” diameter to start with, with that amount of sizing what will that do to the lube grooves will do nothing for accuracy . 1:16 ROT may not stabilize something that long but it might if pushed fast enough, I would expect some leading somewhere in the barrel. The RCBS 170 gr. mould for the .32 cal rifle barrels is very good or a reasonable facsimile of that mould would be a better choice. .32 Special is great cartridge when things are what it’s designed for.
I bought this mold this year through Midway and mine drops bullets .325 or a tiny bit under that using CoWW and pure lead. I've shot it with some good success in a commercial 98 Mauser in 8mm Mauser. Just got a Miroku Winchester 94 in 32 Special so of course intend to try it in that also since the bullet was designed for that cartridge.
