I've found these while diving, they are round and it's definetly not a fishing weight. The line on one of them is a seam from a mold, I know what a split lead for fishing looks like because I go fishing. The artifacts that I have found in the water dates to the 1700-1800's. I was just curious to hear some of your opinions to this. What time period is the musket balls anyway? 1700's or early 1800's? I hope to hear some of your opinions to this... Thank You
