After not visiting my local site for a while I decided to give it another visit, thinking I would not find much more. I was wrong I found a area and I pulled up quite a few 20mm and 50 cal. I also found quite a few 20mm heads (photos to follow) and loads of 20mm and 50 rusty clips, which I left there are they are pretty much useless in their present state. I also found a couple of 50 cal heads, one in very good condition, the other has hit something and appears hollow. The pics are what I found in 4 visits, can't wait to go back.
I also found 2 x 20mm cases with 50 cal cases stuck inside them, they are both stuck solid. I have included a photo of all my finds from the site, I have filled the box and I will need to get another one.
