I have never had a problem with any Eley ammo.
Eley Sport isn't their highest grade but for daily shooting... dare I say, "Sport Shooting"...
Eley Sport will more than fulfill your needs.
One of the main things that differentiates Eley ammo is the prime.
Many manufacturers use a liquid priming compound that is spun into the rim space with centrifugal force then allowed to dry. This produces good results but can cause voids or inconsistencies in the priming.
Since .22 LR shells are so small, the prime can contribute a greater percentage of the total propulsive force of the bullet's detonation. Any inconsistencies in the priming stage will lead to inconsistencies in the final product, possibly leading to an inaccurate round.
Eley uses a dry priming compound that is precisely measured into each cartridge. The powder is tamped into place, under the rim space. THEN, a precisely measured drop of water is added to turn the powder into paste and activate the explosive. When it is dry, the rounds are inspected and weighed. Over or under weight are rejected.
I don't know for sure but I have heard that almost Eley ammo is manufactured on the same assembly lines. The main thing that differentiates most grades of ammo is the quality control inspection. The batches that meet the highest standards are sold as "Eley Tenex". The batches that don't meet the highest standards are sold as "Eley Match", "Eley Club", "Eley Silhouex" or "Eley Sport."
Eley also makes special grades for things like Biathalon which have special cold weather lubes applied. I also seem to remember that the newest batches of Tenex have a specially shaped semi-wadcutter bullet. I don't know. I haven't shot Tenex in a long time.
So, in effect, buying Eley Sport, you are getting the same ammo as one of the higher grades but it doesn't meet the tightest specs. Still good but not the highest grade they sell. You'll probably get good results out of it for the price you pay.
