Between me, my son and my buddy, we have bought seven Lee moulds in the last three months. Only three didn't have to be sent back (or should have been sent back)! I couldn't get a picture to load, but the .44 240 grain tumble lube mould my son just got is more than a 1/64 inch offset! By that I mean the two halves of the mould blocks are offset by that much. Talk about a twin gas leak! (if you could even begin to get them in a case). I have about thirty Lee moulds from over the last couple of decades. Only very recently has their quality control completely gone to pot. Oh, they will send me a new one after a week or two, (and have), but even the replacements have required a half hour or so of tweaking to get them to drop a round, somewhat the right sized boolit so it will go into the sizer centered. Most of the problems have been moulds that would not close so the boolit was four or five thousanths out of round. If you try to size a boolit like that, the lube groove (s) really show the out of round original condition. The other problems have been noticeably offset blocks, in addition to one failure of the sprayed metal cam handle on a six gang.
I have always thought that having a bunch of aluminum moulds was better than having a couple expensive moulds, and that has, up until now, served me well, but I think I am about to completely give up on Lee moulds. They sure weren't made like that when Dick Lee was at the helm.
