I got one of the left overs from the most recent group buy and this is my second mold ever. It's my first Mihec mold and first to be made out of brass.
Today I cast with it for the first time. I noticed it heated up a lot quicker on the hot plate than the aluminum mold usually does. When it hit 330F I poured a few bullets and got wrinkled results, the mold is brand spanking new and all I've done to it is add some lube to the sprue plate hinge. I repeat maybe 4 times total before the mold starts dropping keepers. After that it's smooth sailing, I quickly cast up my 4-20s worth of lead.
The mold is just fantastic, I don't think I will buy anything but brass in the future, maybe cast iron. Never again aluminum that's for sure. In addition to seeming to heat up faster it also seems to retain heat much better. I always have problems keeping my mold hot enough, not today.
The mold drops the bullets at pretty much exactly .432".
Now I can't wait to try out my H&G #68 mold!
