I can tell you the day I started reloading. Jan 20th 1961.
Yet I'm still learning today. I teach a lot of youngins how to reload, and until about their 30s, It seems it takes them a while longer to catch on, then older folk.
Ive been using the same case trimmer (Wilson case lathe) since 1961. I just bought the stand & lock lever last month.
Guess Im getting lazy in my old age.
