I have been using Lee moulds (and RCBS, Lyman, CBE) for the last twenty years. I must have a dozen or fifteen Lees.
They get used a lot, thousands of bullets. Nothing has ever broken. The bullets have proven accurate.
I lube the Sprue plate at the screw with a shot of WD-40; it works and has for the last 20 years.
I used to smoke the moulds; nowadays, I spray them every now and then with graphite mould release.
