Mislabel cartridge Boxes

Hi;
I recently purchased three boxes of 270 Win (Remington 130 gr Sirocco) at the local K Mart. When I went to the range the cartridges would not chamber. Closer inspection showed the cartridges were 30/06 Spr. rather than the 270 Win labeled on the boxes. The boxes appeared unopen and not tampered with. You may want to check your cartridges to verify they are as labeled. It could ruin a hunting trip or even be dangerous. This is the first time in over 40 years of hunting and shooting this has happened to me. Be safe.
