I just bought a second 105SWCLee mold to be able to cast with two 6 cavity molds to speed up production. Cast about 1300 bullets and went to load them after tumble lubing. Lo and behold two different bullets(the old and the new)! New mold has shorter overall length, longer driving bands and a tiny cone nose. Didn't see all this until I cast with it. Called Lee and spoke to tech rep and was told yes, the new molds don't match the old ones exactly. New production technique is the cause of this. Asked him what I should do with a mold that won't work for me. His answer was to live with it, that's the way it is. Some customer service! There is enough difference that when seating a bullet in the press a .030 difference results in the seating depth. The only way to use it is to keep two separate piles of bullets when casting.
