Shooting at sandpits, the rain brings all the lead to the surface. After shooting, I would collect lead for the next casting session. So lead was free, cases last forever(just about), bullseye powder goes a long way. My main expense was primers. I was loading 38s for cheaper than 22s. And that was back in the 70s.
I better head to a sandpit in the morning. We’ve gotten about six inches of rain since Sunday!
