Just bought a box of Remington .30 carbine, and opened the box to find this... Heres a picture of the cartrige in question on the right with a couple normal ones on the left. I've heard that this creates pressure spikes ad is unsafe. Should I take it back for a new box? Looks like with all the extra ammo production, a few manufacturers are relaxing on quality control? Has anyone else found this in their boxes of factory ammo?
