One coil of lead will last me several years. And lead is my prefered weight of choice. I just don't lose that much anymore. Now 15 years ago I could go thru a coil in a couple of weeks.

I don't think lead left on river bottoms by fisherman have that much of an impact. Because of the size nothing is eating it and I don't think it dessolves into the water system??? I think it is just a little lead rock laying on the river bottom forever. Remember it is a natural component. Lead shot however is bad, bad, bad. Gamebirds pick at it to help digestion and then get lead poisening which can then be eaten and passed on to the hunter. I have never used lead shot and never will even where legal to do so.

I noticed that the above link did not mention sportsmen anywhere. If someone knows differently I would be interested to hear their opinion.
