Line 468:
Steel was one of the first widely used lead alternatives that the ammunition industry turned to.<ref name=Barnes/> But steel is one hundred times harder than lead, with only two-thirds its density, resulting in undesirable ballistic properties compared to lead.<ref>{{cite web |url=http://www.unep-aewa.org/publications/leadshot/leadpage4.htm |title=Lead Poisoning in Waterbirds: Alternatives to Lead Shot |publisher=AEWA |access-date=25 Mar 2013}}</ref> Steel shot can be as hard as some barrels, and may therefore damage [[choke (firearms)|choke]]s on older firearms that were designed only for use with softer lead shot.<ref name=Barnes>{{cite book |url=https://books.google.com/books?id=3_-kUkNXTNwC&pg=PA483 |page=483 |title=Cartridges of the World: A Complete and Illustrated Reference for Over 1500 Cartridges |first=Frank C. |last=Barnes|publisher=Gun Digest Books |year=2009 |isbn=978-1440213304}}</ref> The higher pressures required to compensate for the lower density of steel may exceed the design limits of a barrel.
Within recent years, several companies have created non-toxic shot out of [[Bismuth#Lead replacement|bismuth]], [[tungsten]], or other [[Chemical element|element]]s or [[alloys]] with a [[density]] similar to or greater than lead, and with a shot softness that results in ballistic properties that are comparable to lead. These shells provide more consistent patterns and greater range than [https://www.steelshots.co/ steel
