Source for 150 Gr. SWC in .38

I bought some Hi-Tek coated 150 gr SWCs, sized to .356, from Brazos, some time ago. Out of a 14-3 (K-38) revolver, they are a very consistent round out to 50 yards. I've been looking for a replacement and after searching all I can find are 158 gr SWC Hi-Tek coated and sized to .358. I've searched about 14 mfgrs with no success. It appears I would have to cast and coat my own. Curious if anyone has a source for 150 gr Hi-Tek SWCs, or if not, had good success with the 158/.358 Hi-Tek out of a K-38?

Not 150 grain but Bayou Bullets has 158 grain sized to .358.  Bear Creek also has 158 Grain swc, also sized to .358

Good luck

Bulletworks in Texas lists a .38 150 LSWC. I imagine that they may be able to size them for you.

I doubt that they do coating though.

Bayou has one in 9mm (.356) and they say other sizes available on request.
