Last fall I shot an antelope doe and three coyotes with 140-grain GameChangers in a .270 WSM, my daughter shot an antelope buck with a 130-grain GameChanger in a 6.5 Creedmoor. The bullets performed admirably on all counts. Grouping was better than my beloved Nosler Accubonds in both guns. Still, not the best bullet ever, but I would sure take them over a Hornady SST. (for whatever that is worth)
