Gonna start buying a couple of boxes of ammo for my 6920 (1/7 twist) a month. What is the difference in the Win 5.56 (white box) and say, Remington .223 FMJ? The Wolf is $2 a box cheaper. After I bought 4 boxes of Wolf I could get an extra box with the money I saved. Is the Win 5.56 that much better? Is it better than other standard .223FMJ? If you say yes, why? For you info, this is only stocking ammo, for "just in case". But it could be used for self defense someday, if the worst ever happened.
