The advice I'd give is stick with the RFW brands, meaning remington, federal, winchester. There are dozens of euro brands, brands from asia, etc, and you may be able to get good results from them. I won't buy any of them. I've had plenty of experience buying foreign low grade ammo, and with that experience, I choose not to.
I wouldn't buy partizan on a bet. The reason for that is it's made by the arms maker that was involved in the serbian war. Call me a bigot, the serbs committed atrocities and I've not forgiven it yet.
It's all up to you. I wouldn't run steel through mine at all, I have heard too many times that it is dirty, and other issues. Just won't do it. Otherwise, try whatever you want, but be very careful of what you buy and observe carefully for the first box or so to see how well it works.
