The types of shot examined during the project can be divided into three groups:
Metallic | |
Plastic-bound metal particles | |
Chemical-bound metal particles |
In the course of this project, approximately 17 usable types of shot were developed, within the three material groups. Amongst these 17 combinations, the steering committee and the working group selected three types, on which further work has been carried out.
An environmental evaluation has been carried out on the selected types of shot, and these were found to be satisfactory. The fabrication technique has been thoroughly tested and likewise found to be satisfactory, and this is also the case with the work environment.
A veneering test and a processing test have been carried out in a fast outer, and all the types of shot were approved.
The various types of shot have been approved during individual shooting experiments into a gel, in which shoulder plaids from pigs were imbedded (the gel has the same consistency as muscle texture). None of the shot splintered.
Form stability, ballistics and damage to the gun barrel have been tested and found to be satisfactory.
The price has been accepted by the steering committee as being suitable.
Finally, two hunts took place (ducks and pheasants, respectively) in order to test the cartridges under practical conditions. These showed that one of the shot types was acceptable in its present form, but further refining of the shot and cartridge is recommended.
In addition one more of the three selected types would appear to be promising after further development.
