The often-heard advice on .22LR forums is "find the brand of ammo your rifle likes and stick to it." Unfortunately it's not so simple because that's not how it works.
The example shown by the OP is not surprising. Flyers can be common in lesser grades of ammo such as Eley Club. They can be common with other makes and varieties of ammo.
The three major match ammo makers -- Eley, SK/Lapua, and RWS -- each make several "grades" or varieties of ammo. For example, among the rifle ammo, Eley makes Sport, Club, Team, Match, and Tenex. SK/Lapua has SK Standard Plus, Rifle Match, Center X, and Midas +. RWS makes similar varieties.
Each variety of ammo can vary in performance by lot (.22LR match ammo is made in batches called "lots"). Some lots will shoot better than others in the same barrel. The same lot may not have the same performance in different barrels. In other words, a lot of ammo that performs well in one rifle may not do as well in another.
The less expensive each variety, regardless of the maker, will generally be less consistent than the more expensive ones, even in good barrels. That often means more "flyers". There's absolutely no guarantee that the name on the box will assure performance. There can be what appear to be "flyers" in any make or variety of ammo. That is to say, there are lots of the most expensive ammo, say, for example, Eley Tenex, that may not shoot well in a particular rifle.
