Hello Listmembers,

One of my neighbors here in Oakland, CA found a bullet in his yard a few years ago and is curious if one can tell what kind of weapon it was fired from. I'm not an ammunition analyst by any stretch, so I thought I'd put the question out to the many capable historical archaeologists on the list in case any of you is feeling generous with your expertise. (and no, this isn't a "backyard digger" scenario - the thing popped out during gardening and the homeowner is mostly curious if it came from a police revolver).

The bullet dimensions are .356" (9.05mm) diameter and .704" (17.88mm) length.  It has a rounded tip, and two rows of crimp marks from the cartridge at about 3mm and 6mm (or about 1/8" and 1/4") from the base. 

I welcome either ideas as to the type of firearm this came from, or pointers to bullet identification resources. Everything I have in my library/links has to do with cartridges.

Thanks in advance,
Stacy Kozakavich
