Tenex, or Ten-x, is a high quality brand of .22 ammunition manufactured by Eley. Due to its cost, it is used primarily in high level shooting, such as the Olympics or national competitions. Of course, some people with more money than sense may choose to hunt small game with it, however this is widely considered as a waste.
Whilst the round itself is of similar 'construction' to both match and team, each individual round of Tenex is individually scanned and checked for imperfections.
