Bullet Base Stamps
« on: December 07, 2010, 07:56:28 PM »
I'd like to propose a Bullet Base Stamps folder for the gallery.   ;D

In the meantime, here's a few to get things started.

"M": Barnes magnum copper hollow point bullets (mostly 30 cal.), designed to open at high velocity and not break petals. Info from SHOT Show 2010: Barnes rep. Chandler Bates.
16174-0

"X": Barnes super high velocity copper hollow point bullets, designed to open at high velocity and not break petals. Info from SHOT Show 2010: Barnes rep. Chandler Bates.
 
16176-1

"T": Federal tactical 223 rem 55gr soft point. (from box)
16178-2

“T” originally was on Trophy Bonded Bear Claw bullets which Federal loaded.  I saw them manufacturing the bullets at Federal on a tour a long time ago and I think they acquired the rights to sell them in loaded ammunition (not sure on the specifics here).  Federal still lists the bullet being available  in a variety of big game calibers (Vital-Shok line – now with polymer tips).  It looks like Speer is selling the bullets for reloading now and they have calibers ranging from .224 to .475.  I have not seen these, so I don’t know if they still bear the “T” on the base. They may be available as components or in loaded ammunition from other sources that I don’t know about.  Ashely is certainly right about the listed load bearing a “T”.  I just wanted to let those who might not be aware that you could run into the “T” on other loads and calibers.

Ashley,

Great idea.  If possible, I would suggest a photo of the box of ammunition also.  That would help with case documentation.

Also, if any AFTE article has been authored on the topic, a citation of the article.

Test fired a .22 five times in the tank using Remington High Velocity 22 LR ammunition from lab supply.
 
22382-0
 
Noticed with interest that each of the test fired bullets had a different bullet base stamp...
 
U,Y,R,W and an H (or U,Y,R,M and an I?)
 
OR
22380-1
 
It's like bullet ouija! Apparently I need to shoot more to get the rest of the message...  :D
 
(Yes this is a blatant thread bump to try and weasel a bullet base stamp folder into the Headstamp Gallery. ;) )

Sounds like a good idea.  I'll get a folder started for it in the HSG.  I'll include a link to Evan's previous thread about the CD with additional photos.
 
Thanks, Ashely, for providing the start-up photos!  :)

Evan,
 
Could that information be placed into a PDF document to shrink the size and info to something that could be posted and printed off if needed for court?
 
Thanks
Chris

I believe the Trophy Bonded Sledgehammer has the T on the nose of the bullet.
