For just general break in, I would just use some good quality surplus military loads. Find a type that uses a copper jacket though as opposed to steel if you are worried about excess wear. This should be as good as anything for breaking the gun in and it won't cost you a fortune.
One thing about moly bullets, don't use them unless that's what you plan to always shoot in your rifle. I had a couple of folks who are wiser than me tell me this. I can't remember exactly what the reason was, but I am sure it was something worth considering. Maybe someone else can chime in here with the details. I hope I'm not totally lost on this, but I am pretty sure I have heard this said before.
And yes, Black Hills loads some great ammo, but I would save the top notch stuff for serious shooting as it is gets very pricey after you buy a few boxes.
