But ammo buyers need to be aware that not everything is as it seems and not all ammo is created equal. I found this Winchester "150 Round Value Pack" of 9mm NATO 124 gr ammo for sale at my local Gander Mountain for $49.99 recently. That works out to about $16.66 per 50, which is not bad for reloadable brass cased 9mm in the current market. That is, until you read the (very) fine print on the bottom of the box that says, "These cartridges are loaded to military velocity and pressure; average pressure is 10% to 15% higher than industry standard pressure for 9mm Luger." This is obviously part of some military contract overrun packaged in bulk as cheap plinking ammo. The problem is the "10% to 15%" higher pressure puts this square in the 9mm +P category. The Sporting Arms and Ammunition Manufacturer's Institute (SAAMI) actually goes as far as to list 9mm NATO as being "unsafe" for firearms chambered in the standard 9mm Luger caliber.
