Very interesting... I found something very similar the other day in a farm field also. At least I think thats were you said you found it WT. What I have is also lead and tear drop shaped. It first thought it was a fishing sinker but it also has no eyelet for line. It was found at a site that was gone over 125 years ago, everything I dig at this site is old. My best guess would be some type of hem weight. ?? Mine seems a little smaller then yours WT. Non pointed side appears to have a flat spot with two small groves. Patina on what I have doesn't look over 125 years old though.
