Unfortunately this is a pricey part of the game, and you and your gun will dictate what you need a lot more then the internet will.
I would suggest looking for partial boxes of ammo, bullets, powder etc. Your rifle will show what it might like fairly fast, or you can at least eliminate what it doesnt like.
What you want to do with it will dictate the bullet construction/ ammo you will want - target shooting, long distance, or hunting, and what are you hunting with it?
Narrow down your intentions with this rifle and we can help a lot more.
For reloading, as mentioned H4350, H4831SC, superformance are all good to start to play with. Once again if you can find 1/2 lb its cheaper to start.
