New grendel, wont fire

[Jamie45]

if it is simply it not liking hornady, Ill start right off with reloading, I just need to find this out asap so I can get going, need to use this thing in 1mo in cali... Everyone is so far away.

What other ammo should I buy to try? what works in everything? Or someone mail me some reloads or something? I really really appreciate the help all!

If you can get over here, I can hook you up with some trial ammo. I have AA, BH, wolf & Hornady on hand.
