My all time best day was in a new camp a friend and I came across in Rolla, Missouri. I was working third shift as a restaurant manager. I got off at 6:00 AM, took an hours nap, drove an hour to the new camp and hunted until I dropped. I had a pouch full of bullets which I cleaned after I got home. The final tally was 95 bullets. If I had known I was that close, I would have gone for a hundred.
I love hunting "hunted out" camps. I went back to one this Winter and started to work it slowly and meticulously. I have hunted about half the known camp before the grass got too tall and dug nearly 200 bullets out of it. Over a hundred were .36 cal. teardrop bullets. The owner told me he gets two to three hunters every Spring and Fall who hunt for awhile and quit with a total of two or three bullets. Persistence DOES pay off. There are limits, but my recommendation is know what a deep bullet sounds like in all metal. I dig lots of iffy signals in discrimination, but listening to the all metal sound gives me a huge edge. As I posted earlier, I've dug over 600 bullets this year. I have a couple of good spots that are producing for me right now, and I'm sure I'll "hit the wall" soon with them and will struggle to get finds, but I'll deal with that when it comes.
Bottom line, the easy stuff is gone, but the left overs can be very nice. I've found 12 of the .38 cal. Sharps multiring bullets. Sold one on eBay for $62. Traded four of them plus some teardorps for a 3" Parrott artillery shell. I found an 1853 one dollar gold piece in a "hunted out" camp. I love digging Civil war relics. Even shot bullets give me a kick.
Be glad the old timers are telling you where their good spots used to be. The equipment is better today, and when the finds were easy, they generally didn't concentrate on those iffy signals. They left a lot behind. Hone your detector skills and keep on diggin'
