Had to look for my loading data. I shot everything (factory) that I could find locally. I thought it was only Hornady stuff but my brass is about equally divided between Hornady and Federal. Only a single reload tried Hornady brass, Federal 205M the Nosler 100 Ballistic Tip and H322. Hodgdon H322 might not be the best choice but of what was on hand it was the most logical. My rifle so far has shot everything tried in it very consistently but nothing out standing. Part of my ambiguity about it's useage. Two and a half years ago when trying to pick up a set of dies I couldn't believe RCBS didn't even list the 6.5 Grendel. RCBS list dies for things I've never even considered but not the 6.5. So I ended up with Lee. I think Hornady listed them but I dont care for there dies. I definitely need to play with this some more.
