Craig, you misunderstand....
....I'm DEFENDING the continued use of lead shot for those birds we can still legally shoot with lead. Until someone shows me that ingestion of lead shot is killing lots of upland birds, or is killing some species with declining numbers, or is killing eagles. Nothing I've seen shows me any of that.
I know you're defending lead shot use in the uplands Larry. That's a great thing, no complaint from me.
You have though lobbied heavily that lead shot and bullets is the only reason for lead poisoning deaths of other wildlife, and of course the uplands are immune. Try to separate yourself from the narrow waterfowl/lead shot topic, and see if you can 'prove' that deer hunters should thrown under the bus by upland lead shot bird hunters.
You said, 'didn't intend to mention any studies' back a page. If I don't want to site studies or bring in a biologist, will you accept my logic and feelings as the equivalent of yours?
