“I recently purchased a bolt action Howa Mini Action 6.5 Grendel. So far I have fired Hornady Black 123g ELD match & Federal Fusion MSR 120g, at 100 yards. Both shoot less than minute of angle. With my cheap Vortex 2-7 scope, I can not tell which one shoots the tightest groups. I can tell you that Hornady Black is target ammunition. Federal Fusion is proper ammunition for deer and hogs. I have not hunted with either in 6.5 Grendel. I have hunted deer & hogs extensively using Federal Fusion 115g. 6.8SPC ammunition. With heart/lung shots on deer, they usually drop where they stood. I expect the same from 6.5 Grendel.”
