I too get consistently best results with Eley Tenex, with R-50, Gold Ultra Match, and Lapua Midas a close second (and often surpassing the Tenex). (Winchester 52's, M2 Springfield, Martini, and BRNO sporter.) The thing with Tenex (and the rest) is the aforementioned variation from lot to lot. Experiment until you're satisfied and then go back to the store and buy every round they have of that same lot.
