Surplus lead solder
Should I continued to use my 1 pounds (2.2 kg) of Kester lead tin 60%/40% solder? The silver based lead free solder are becoming more available. I still have a pound of lead solder that I inherited and the solder dates back to the 1950s. These are for my electronics hobby stuff like op amps and 555.

As long as the flux is still working (which I highly doubt), I see no reason why is can't work.
However, I am a lead free guy. Since all my soldering gears are designed for lead free, I don't see much benefits from using leaded solder anymore.
Some say lead free solder uses higher temperature, hence more toxic flux fumes, but since I use a non-adjustable soldering iron, it works at same temp regardless leaded or lead-free, so it doesn't matter.
Leaded solder has reliability advantages, but I guess for hobby use, it doesn't matter anyway, unless your hobby project makes its way to ISS.
