Got to be tough to survive the inner city's. I have found hundreds of pounds of 30 and 50 cals on the base I hunt...you can look at the bases of every tree and bush and find several I've thrown there after digging them up so I dont dig them again. The 50 cal bullet reads as a quarter...every time I detect one I hope its a quarter. They ring out the same, but the bullet is a little stronger.
