I just made decision to thin everything way down. I’ve got 100+ sets of dies, not including doubles of several. Not junk tools all top of the line. I been loading since a kid. I decided one time when I was in my 20s to never sell dies, unless multiples. I had sold a rifle with dies and it wasn’t a week before I ended up with another rifle and had to buy dies again. I’ve decided to sell the dies I no longer have a gun for. Starting with dies that I no longer want a gun for. I put up military dies, magnums and some odd balls first and have sold quite a few. I been selling guns too. A hard decision to make but we are all going to have to face it at some point. As far as mental capacity, it’s on individual basis. I know several people who never had the attention span or IQ to reload when they were young.
