Since no one has chimed in, here I go. If you asked 10 different people here about the ammo they use and what works and what doesn't from factory to hand loads you would probably get 10 different answers and they may all be right. I suspect if you stick with the usual suspects, Hornady, Winchester, Remington, Fiocchi etc.. that it won't take to long to find a load that your rifle really likes and some that it doesn't, and then if you decide to hand load you can tweek even further.

My only suggestion would be not to break your barrel in with garbage ammo. Why? It just makes me feel better.
