Have you ever look at the bottom of your bullets? Usually you see an indication of the brand, so big deal, of course you know the brand, you removed it from the box. What if you’re going through some old stuff and encounter some loose rounds with head stamps you have never seen before and you start to wonder.
I recent question by huntfishtrap on the Outdoor Life forum asking about some .22 LR rounds his Grandfather had; this had an HP stamp. As a young man I burned a lot of those Hi-Power Federal rounds so I knew that one well. Then I got to thinking there are lots of ammo companies no longer in business or they have changed their logos, so how would one go about finding this information.
After some extensive searching I found an interesting site The Association of Firearm and Toolmark Examiners here they have galleries of head stamps where you can look up head stamps and see images of them or if you have one that is not there yet it can be uploaded. A great historcial archive!
