We just arrived at my wife's daughter's house in southern New Hampshire and I took the Excallibur out for a test. She has a few acres in an old farm area. The area was pretty clean. No hits at all. I went down an overgrown trail through the woods and found an old cartridge about 6 inches down. As an avid shooter, I had never heard of this calibur. It was a Western 38-55. Found that it was the predecessor of the 30-30. Probably over 100 years old based on the occupancy of the area. I also located some square nails and some cut nails. Tried a small family plot on the property and nothing near the surface. Do not dispair, I didn't go in there with the idea of digging up gravesites! It was their understanding that most of the gravesites were removed at some point in the past and relocated to proper cemetaries. I will continue searching the area for other artifacts. The area was developed in the mid 1700's.
