Thanks, I was leaning that way. The friend that gave them to me was going to hunt with them. He put one in the chamber and it wouldn't extract. The bullet pulled out of the brass. The bullet got stuck and had to be pounded out with a cleaning rod. Good thing he didn't see something to shoot at that day. I measured the bullets and they are .308 dia. and tried one in my 1903 and it extracted fine. I don't know why it got stuck unless it's because the length is to long for his rifle. Thanks again, I'll be pulling them apart. Would you change the primer too?
