Hello all - all my new molds are Lee molds, mostly 2 cavity. I've been having problems with the mold not casting the same weight bullets all the time, finally checked and it's either the front or rear cavity that's light, sometimes only a couple of grains, but worse mold had around 4 grains difference. Is this common for Lee molds? Do NOE, or other "high dollar" molds cast the same weight bullet in both (or more) cavities?
I took a bullet and polished out the light cavity and got a couple of the molds within <1 grain of each other. Now they're not the same diameter, but this should be taken care of in sizing after powder coating.
I'm wondering what other folks experience with multi cavity molds are. I've got an old Lyman 358156 dual cavity mold I've had since the '70s and it's <1 grain difference.
