Thanks! I've been finding them from the early to mid 1900's. This one seems to be a little older.I must confess my "ignorance" concerning old brass shotgun shells goes.I am beginning to have more "respect" for these often regarded "trash" items though as they can provide dates for other prospective targets in the area you're hunting. Any target that can provide research material for dating sights should be considered a "good" recovery in my humble opinion. I'd say you have an "old" one and should continue hammering that sight for the "better" targets.
