Our fibre formulations have been specifically developed to perform in shotgun cartridges.
Using cutters tipped with a specialist alloy containing one of the hardest materials on earth, Vanadium, we produce an extremely round, cylinder shaped wad, to tolerances of just five one hundredths of a millimetre.
This promotes a tight fit in the cartridge and an effective seal which is further enhanced upon firing, when the fibre ‘squashes’ very slightly against the cartridge wall.
Independent metrology service provider, Measurement Solutions, investigated a range of dimensional characteristics to determine the dimensional accuracy of 25 randomly selected Envirowad fibre wads as well as 25 samples of their closest rivals.
The results show that Envirowad is over 60% more dimensionally accurate than its rival.
A perfect circle and a perfect cylinder has zero deviation i.e. the closer to zero the value, the rounder and the more cylindrical the wad. In nearly all cases, Envirowad was closer to zero than its competitor.
In addition, the dimensional accuracy of the competitor wad varies more greatly and frequently than the Envirowad product.
