Eley releases new .22 round – with a black cartridge case

Top rimfire ammo firm Eley has released a new twist on its award-winning Tenex ammunition, featuring a black cartridge case.

According to a press release from the company:

This advanced, contemporary cartridge is instantly recognisable by its matt-black oxidised finish. Scientifically developed to microscopically increase the friction between the case and the projectile, the resulting stabilised projectile release force delivers greater internal ballistic consistency ultimately providing the shooter with more consistent projectile flight.

The round itself uses what looks like the existing Tenex bullet and a cartridge case that is otherwise unremarkable. Eley’s performance data for the round shows it’s pretty much a standard .22″ LR load – 40gn bullet, 1085fps muzzle velocity, 1″ COAL.

UKSN’s author thinks it’s a bit of a marketing gimmick, though a pressure/velocity increase delivered through increased neck tension could well have a beneficial effect. Or the opposite – YMMV.

Check out the full press release, with accompanying drawing, on the Eley website.
