Mine's bigger than yours!

With the weather, the rugby and other commitments, there has not been much to report on the treasure hunting front for the last couple of weeks. I thought I would post some of my more 'unusual' finds from the previous few months detecting.
This one is the biggest bullet shell I have ever seen, a .50cal I believe. It was dug in a local park that was originaly part of an army rifle range up until about 1950. I have put it next to a standard WW2 .303 case dug in the same area for comparison. The headstamp is RA 42. Made by the Remington Arms Co in 1942.
