While I like my Mihec molds and marvel at his machining, brass is my least favorite material for a mold as I find it is the goldilocks material in terms of having the narrowest range of not too hot and not too cold to cast good bullets.
And yes, I have a couple of the 4 cavity molds and they are heavy mo-fo's. I would much rather they were made from meehanite and I likely wouldn't have sold my 476640, but as it was I simply couldn't get the right temp where I was hot enough to get the noses would fill out or too hot so the base would be damaged when I dropped the bullets from the mold.
