Hi, I've been testing lots of the above ammo in TC R55 Benchmark Classic recently (RWS Match, Club, Eley Sport, Action, Club, SK Match) and finally the Geco semi-auto, as it the cheapest but it shot as well as the best more expensive RWS, grouping 10 well inside sub 2" @ 100 yards. They are a bit waxy and can FTF when the guns cold occasionally but the TC does have a notoriously tight chamber....I really rate them!
