There is a common misconception that buying a premium brand ammo means that it is loaded to a higher standard or held to tighter tolerances and will therefore tend be more accurate. The actual truth is that when you buy premium ammo the real reason for the difference in price is that it is typically loaded with what is regarded as a premium type bullet. Ballistic tip, Nosler Partition, Barnes TSX, etc, etc. Where as the basic blue box federal stuff (just to name one brand) will have a simple standard lead tipped bullet. So whether you realize it or not you are paying that extra money to get a more expensive type of bullet. Not a more accurate cartridge. A given rifle is just as likely to shoot some of the cheap stuff well as it is the expensive ammo. Unless you actually need or just want one of these more complex designed bullets there is no need to purchase this higher dollar stuff. For deer, standard lead tipped bullets have always been and remain all you need.
