the mold is supposed to cast a .357cal 148gr wad cutter. I started weighing them all just as a sanity check. I weighed about 90 and found I had six distinct piles. a low weight of ~141gr, a high weight of 158gr. I had an occasional outlier which I would expect. It looks to me like each cavity produces a unique weight, none of the cavities are the same. This was all with lead that came from the metals dealer with the metal works stamps on it which included 0.999 pure Pb. All were cast from the same pot with no antimony added, and the metal being fluxed periodically. Is it reasonable to expect to get 6 widely differing weights? I have a Lyman 2-cavity mold that gives me 148.3gr from each cavity consistently. Thanks for any opinions.
