I'm new to collecting and am having trouble finding info on a 30-06 cartridge I have. The headstamp is marked TW and 54, which I understand, but it's got an odd bullet tip. The main body of the bullet looks like a standard FMJ copper color, but the tip appears to be a separate component, is the same color as the brass case, and is somewhat loose. I've got some AP rounds that have the black paint on the tip, but there's no paint on this one. Any help would be appreciated. Thanks, Scott.
