Occasionally Ebay or Gunbroker has Lyman/Ideal 350447 (180gr GC) or 350482 (250gr GC) available.

In lieu of ordering a custom mold, you could try carefully sizing down suitable flat nosed .358 boolits with deep grease grooves to .350. Go slow in stages and start with boolits lubed, so the grease grooves are packed full before sizing down. Using an intermediate (9mm/.355) sizing step would help.

Another downsizing option would be to custom order a Lee push through sizer in .350. Starting with prelubed and gas checked .358 boolits, you may be able to size down to .350 in one step. You have to go slow and might need to smear a viscous lube on with your fingers. I use either Imperial Sizing Lube or STP (the engine oil additive) to size from .338 to .330 in a Lee sizer, and have even done so with .338 bullets with thin jackets. https://leeprecision.com/custom-clas...izing-kit.html

Since you're just starting out, you'll need to price your options out and assess your skills to take on more complicated processes. It's much easier for us old guys to improvise, since we've been at this for decades and have accumulated garages full of reloading and casting "stuff."

Remember that the .348 has an extremely shallow throat. Make sure your crimping grove is far enough forward so that the slug doesn't jam into the lands of the rifling when chambering the cartridge.
