I've been using Lee bullet molds since the early 1980's & they still work fine. Not long ago I bought a new Lee mold & it has two steel cross pins for alignment of the two half's. After heating up the mold & casting about 10 bullets I noticed the two alignment pins had become finger loose & had been pushed back into the left mold side. Also read where another caster was having the same problem. Lee sent me a replacement mold which I have not used since. Anyone aware of this problem? Has Lee come up with a fix or is this still a problem?
