I am an archaeologist working at a WWI training camp located in the California Bay Area. I came across a few unique .45 ACP bullets and have some questions concerning them.
1. This bullet has a circular hole in the jacket and I was wondering if this was some kind of tracer or incendiary bullet, or maybe just an odd impact mark?
2. These two bullets have a series of unique crimp marks - 6 short linear/rectangular crimps just above a cannelure crimp line that goes all the way around the bullet. I am familiar with the 3 circular crimps used for the .45 revolver, but this style of crimping is new to me. These bullets also appear to be tinned. Is this crimp style dateable?
3. These bullets have a "U" stamped in the base of the lead core, and I was wondering if anybody had seen these before. Is this a Remington U.M.C. stamp? Also, is there a more specific date range associated with these stamped bullets?
Thanks for your help.
