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
Hollow-point bullet Hollow-point bullet A hollow-point bullet is an expanding bullet. It is used for controlled penetration, where over-penetration could cause collateral damage (such as aboard an aircraft). In target shooting, they are used for greater accuracy and reduction of smoke, fouling, and lead vapor exposure, as hollow point bullets have an enclosed base while traditional bullets have an exposed lead base. Plastic-tipped bullets are a type of (rifle) bullet meant to confer the aerodynamic advantage of the spitzer bullet (for example, see very-low-drag bullet) and the stopping power of hollow point bullets. When a hollow-point hunting bullet strikes a soft target,
