Yes, for competitive shooters and serious hobbyists chasing tighter groups, ELEY Tenex is worth it. A box of 50 typically costs around £17.80–£17.90 from UK retailers, roughly 36p a round, a premium over standard-grade .22LR in exchange for a maximum radial standard deviation of just 3.75mm and consistent velocity between 317 and 330 m/s: the same specification used at Olympic and World Championship level. That batch-to-batch consistency is why national teams and world record holders load it.

For casual plinking or general practice, a standard-grade cartridge will do the job at a lower cost per round. Tenex earns its price for shooters who need to remove ammunition as a variable at the highest levels of competition.
