The best "bang for the buck" rounds have been SK Standard Plus and Eley Target. Roughly 12 cents a round, and the accuracy has been fantastic. MOA with relative ease, even out to 100 yards. My absolute best accuracy has come from Lapua Midas-X. But you're talking 30+ cents a round, and the accuracy is only slightly better. Honestly, the SK performs so well, that I use it for NRL22 events and benchrest competitions.
