title: Antimony content of inorganic gunshot residue (IGSR) produced by 0.22 caliber rimfire ammunition having free-antimony primer.
abstract: In a recent paper published in Forensic Science International (FSI), Lucas et al. (2016) claimed that muzzle discharge of 0.22 caliber rimfire ammunition is more likely to incorporate particles from the bullet surface than those retained on the firearm and that characteristic particles containing Pb, Ba and Sb formed from known Sb-free primers are likely to be more prevalent in muzzle discharge. It seems that this claim is not based on sufficient experimental results.
