Be carefull... a friend of mine died by stuff found there. He was very experienced with ww2 ammo .... but not enough.
If you are not used to handle this ww2 stuff, you should stay clear.
In the eighties I did find tons (literally) of that stuff. And there is still more than you can imagine.
Did you ever make it over to detect? If so, how did it go? I was in Normandy in June and saw people (without detectors) kneeling on Omaha Beach digging in the sand...
