I've been happy with the remington green box ammo, but it's fairly expensive. About $35.00- $40.00 a box around here if you can even find it. Now that I have enough used brass though I have been reloading it for about 50 cents a round using 405gr remington bullets and RE#7 powder. Don't remember my exact recipe off the top of my head though. Think it's around 47grains, but don't quote me on that. I'm sure you could drop your cost even more using lead bulletsif you do alot of shooting.
