Unleaded hunting: Are copper bullets and lead-based bullets equally effective for killing big game? - 2019
Data show that animal flight distances for roe deer, red deer, brown bear, and moose dispatched with lead- or copper-based hunting bullets did not significantly differ from an animal welfare standardized animal flight distance based on body mass. The relative killing efficiency of lead and copper bullets is similar in terms of animal flight distance after fatal shots
Lead Exposure in Bald Eagles from Big Game Hunting, the Continental Implications and Successful Mitigation Efforts - 2012
Eagles had significantly higher lead levels during the hunting season compared to no blood lead levels during the non-hunting season. The use of non-lead ammunition significantly reduced lead exposure in eagles, suggesting this is a viable solution to reduce lead exposure in eagles.
Analysis of number, size and spatial distribution of rifle bullet-derived lead fragments in hunted roe deer using computed tomography - 2023
This study highlights the challenges of ensuring sufficient removal of lead-based rifle bullet fragments in game meat processing for either human consumption purposes or for use as pet food.
