Fishing sinker effects of tungsten, however, are essentially unknown. More recently, terminal tackle manufacturers are experimenting with high density composite resins. These materials present a non-toxic alternative to lead sinkers at a lower monetary cost than alternative metallic sinkers. Fishing sinker A fishing sinker or knoch is a weight used in conjunction with a fishing lure or hook to increase its rate of sink, anchoring ability, and/or casting distance. Fishing sinkers may be as small as 1 gram for applications in shallow water, and even smaller for fly fishing applications, or as large as several pounds or considerably more for deep sea
Cast bullet Cast bullet A cast bullet is made by allowing molten metal to solidify in a mold. Most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity. Most commercial bullet manufacturers use swaging in preference to casting, but bullet casting remains popular with handloaders. Firearms projectiles were being cast in the 14th century. Iron was used for cannon, while lead was the preferred material for small arms. Lead was more expensive than iron, but it was softer
