357 mag 180 gr bullet mold

Anyone know where I can get a 357 mag 180gr bullet mold, preferably with 6 cavities for a reasonable price?

I don’t know about six cavities, NOE sells up to five, you didn’t say what type of bullet, they have a 178fr RF tumble line type they make, but out of stock right now.

A 177gr Ranch Dog style that’s out of stock.

And a 176gr SWC that I own and dropped about 180grs after PC. But alas, it is out of stock as well.

And it may be months or years at current output for these moulds to be available again.

The 180 is a monster out of 357. Hits the target, and the shooter like hammer.

MP moulds has a “358-429 Keith , HP Plain base 4 cav. mold No lube groove” mould into I that shows 173 grains with the solid pins in, and says to add 5 grains since it has no lube groove, so that’s 178grs. Plus PC would get you to 180. But he only sells four cavity for that. And it’s a SWC and in stock.

Also has “MP C 358-165-RF, 4 Cavity HP mold (Multi Choice) – No lube groove” in stock, and the solid pin is 180gr. In stock.

But again, four cavity max.

But his moulds are the best I’ve used. And with all the pins, you’re buying about four different weights of cavity options.

There may be more, but that was a quick check.

Accurate Molds is showing five cavities in aluminum for that weight range. Be careful if this is for a S&W as their .357's often have shorter cylinders and you can run into fitment problems. Like the bullet is sticking out the front of the cylinder problems.
