I finally pulled the trigger so to speak and ordered a Lee 356-120TC six cavity mold for my daughters 9mm. It arrived yesterday afternoon on the Brown Truck and I just had to heat up the pot and give it a try. I've got to say that I'm impressed. The six cav molds from Lee appear to be of a substantially higher quality than the two cav models. The sprue plate didn't need to have the edge knocked off of it to prevent carving up the tops of the mold blocks and the overall quality is very good. I like the fact that it doesn't weigh a ton either, about the same as a Lyman iron two cav mold really.
Unfortunately I made the mistake of following Lee's instructions regarding cleaning it and just used lighter fluid and a Q-tip to clean the cavities. It wasn't the brightest move I've ever made but I was impatient to use it and didn't want to use my faithful Dawn and hot water. The first twenty or so pours gave some pretty wrinkled up boolits but once it "seasoned" itself they started dropping really nice. A couple of observations:
Once you get going with one of these things you can really pump out some boolits!!
Also, I'm gonna have to use a wet rag to keep the mold cool from the looks of it. A six cavity mold even if the boolits are only 120gr will get extremely hot. So much so that even after the sprue hardens and frosts you can still have molten alloy under that sprue plate.
And lastly I was surprised at how big the boolits drop out of this so-called .356 mold. The weights are right on the money (123gr +/-) but the boolits are dropping at .360-.362 which kind of surprised me. Alloy is COWW +2% tin.
