  • How Good Are Copper Bullets, Really???
    How Good Are Copper Bullets, really??? by Carl Batha, Certified Wildlife Biologist Wildlife Biologist (retired) & Phil Lehman Wildlife Technician (retired) Funding was provided by the Wisconsin Department of Natural Resources, 2 This project started with the purchase of a new rifle in 270 Winchester caliber. Since I had no ammunition in this caliber on hand, I decided to handload copper bullets to better familiarize myself with them. I hesitate to admit that it has been only recently that I have educated myself with the published articles that clearly show that upland game are being impacted by the deposition of lead from hunter‟s cartridges and shells. I was embarrassed to admit, even to myself, that as a practicing wildlife biologist I let this part of my professional knowledge lapse. As the foremost stewards of the resource — and I believe that to be sport hunters — we ought to be doing better. Recently, there has been a surge of activity regarding lead particles in game from hunter-shot animals and the consumption of that meat with resulting human health concerns. No, a direct correlation has not been made between game consumption and human lead poisoning, but the corollary facts are there, so who wants to take a chance!! Thirty-eight years ago, about the time I was starting my career, lead poisoning in waterfowl was the issue of the day. I am proud that the Wisconsin Department of Natural Resources took a leadership position in outlawing lead shot use in waterfowl hunting. Yes there was resistance, but there also was active dialog and training conducted with hunters by the agency.

    Bob Smith (cc Bernabei, leech) re your 12/8 and enc. 12/7 12/9/71 Pursuit of the tracing of the pistol strikes me as a rather worthwhile research project. Perhaps you can also go further with the rifle order than Hoch and I have, but I think you may want to check my file on this. I also think Paul's recollection will be much better than mine on this. worked on it together and he has copies of eveyything I have. A general comments Bernabei ie an authentic expert, and I think you should send him a copy of your 12/7 memo with attachments (I have not time now to read the attachments but I respond in order that this not get forgotten in the press of too many things). What may seem reasonable on the basis of logic may not be on the basis of ballistics, for example. I am sending him the carbon of your 12/8 to we. What Hoch and I have includes even the copies of the Pegazines the Fitt dusted (negatvely as I recall) fromAlba and reports (inadequate) on the tracing of the magazines there. It seems to me that there was a mysteriously, pretendedly official visitor before the FBI. An assortment of people, including Garrison and I think Sprague, have conjectured that some kind of explosive ammo was used. Leon Davidson postulated ice bullets. I see no reason for anything like these farout things, particularly not if the Pi-C was planted to be found and was not used, as is my belief.

  • Lead Ammunition: Toxic to Wildlife and the Environment
    Lead Ammunition: Toxic to Wildlife and the Environment Humane Society of the US Though excellent alternatives exist, lead ammunition continues to poison wild animals and the natural world Lead is a toxic substance that kills millions of animals each year and contaminates land and waterways across the country. Because of its toxicity, lead has been removed from paint, gasoline, water pipes, and a host of other items to protect human health and our environment. Yet it is still the most common form of ammunition that hunters use. The U.S. Fish and Wildlife Service began requiring non-toxic ammunition in hunting migratory waterfowl in 1991 after biologists and conservationists estimated roughly 2 million ducks died each year from ingesting spent lead pellets. Yet more than 130 species are still vulnerable to the toxic effects of spent lead ammunition. There is overwhelming scientific evidence on the toxic effects of lead ammunition on humans and wildlife and broad support for eliminating its use. Questions and Answers about Lead Ammunition How does lead ammunition poison wildlife? Wildlife can fall victim to spent lead ammunition through two avenues: Primary poisoning - an animal ingests spent ammunition (or fragments of ammunition) directly from the environment, usually when foraging for food on the ground Secondary poisoning - an animal consumes wounded or dead prey or scavenges gut piles contaminated with lead ammunition left behind by hunters Both avenues can be lethal to wildlife. For those who survive, they often experience long-term, negative effects that make them more susceptible to predation and dangers like car collisions. An estimated 10 million to 20 million animals die each year from lead poisoning in the United States.
