I bought a Lyman 45 in 1958 and it is still a good functional machine today. I also own three Lyman 450s and they all give good service. I have had a couple of glitches over the years with these machine, but every time it was my fault. Either I wasn't paying attention or I was asking the machine to do something for which it was not designed.
I keep one 450 filled with my own home brew, one with Felix and one with beesway/moly grease combition. I avoid store bought lubes like the plague. Don't get me wrong, I am certain there are some fine lubes out there, it is just kinda unseemly to buy lube. Makes it sorta hard to look fellow hard core boolit casters in the eye.
