Tungsten alloy shot is used as the shot of shotgun, hunting sphere. A shotgun is a firearm
that is usually designed to be fired from the shoulder. The shot pellets from a shotgun
spread upon leaving the barrel, and the power of the burning charge is divided among the
pellets, which means that the energy of any one ball of shot is fairly low. In a hunting
context, this makes shotguns useful primarily for hunting birds and other small games.
Experience shows that hunters and other interest groups have a number of concerns
with respect to the change towards non-toxic shot. The following advantages and
disadvantages of substitute products have been communicated to the AEWA
Secretariat by representatives of national hunting organizations within the AEWA area:
Steel:
• at least 30 % restriction on shooting distance;
• problems with respect to older guns;
• serious problems related to duck and geese shooting from a distance of more
than 30 metres (e.g. crippling losses);
• ricochets on water and hard surfaces, trees and wet branches;
• dental problems after consumption of game containing pellets;
• problems with machines in food production;
• lack of availability.
Bismuth:
• at least 25 % restriction on shooting distance;
• higher prices compared to lead;
• lack of availability.
Tungsten (soft or hard):
• very effective and even extended shooting distance by 10-15 %;
• no reports about ricochets, crippling of birds or dental problems;
• higher prices compared to lead;
• problems with respect to older guns in the case of the hard version;
• lack of availability.
Tin:
• inefficient;
• lack of availability.
Zinc:
• toxic;
• lack of availability
Why use tungsten alloy shot?
High density, great hardness and resistance to high temperature make tungsten to be one
of the most sought-after materials for
of tungsten alloy is about 18g/cm3, only gold, platinum, and a few other rare metals have
a similar density. So it is denser than any other shot materi
bismuth. To understand how the density factors into performance, let's look at two spheres
about the same size, a golf ball and a ping
fly farther and hit harder. Now reduce that
and the other a tungsten alloy. Get the picture? The tungsten will fly farther, hit harder and
penetrate deeper. That means more birds, farther out, with fewer cripples. Another unique
property of tungsten is that it is non
people to handle and work with.
