The
Little Devil
The following rimfire
cartridge case was recently submitted to our
laboratory requesting identification. The case is flattened
and the head is blown out, but there are remnants of the
Winchester Super-X headstamp on the outer edges of the head.
Because of the deformation, it is difficult to distinguish
caliber, but it appears to be consistent with the 22 to 27
range. The overall length of what remains is approximately 0.5
inches.
There is a scored line
around the circumference of the case body and evenly spaced
scored lines at the mouth reminiscent of a star-crimped or a
blank load. Additionally, one side of the case body bears a
very peculiar mark. The mark resembles an "evil smiley
face" with the top edges of the eyes continuing onto and
connecting on the backside of the case.

I've included a
side-by-side size comparison photo with standard 22 caliber
cartridges as well as 22 and 27 caliber powder actuated tool
loads from our SAF.

I've contacted Winchester
and they have assured me that this is not their doing. It
could be a custom job or just someone with too much time on
their hands, but the mark is very uniform in its depth and
design. Any help in the identification of this cartridge would
be much appreciated.
Caution: Staring at this image for long periods of time
may cause one to think impure thoughts!

Lead
GSR Testing On Carpet?
I have a
sample of green carpet with a couple of defects in it and am
conducting GSR testing. After processing for lead
residue a nice big purple color change comes up. It was
one of the biggest areas I have ever seen.

(Click image for larger view)
I get
suspicious and get my technical reviewer, Mr. Ron Crumley, in
and ask him to look at what I had just developed. We
decided to process a control area of the carpet and it also
comes up just like questioned area but only a lighter purple.
At this point
Mr. Crumley and I put the components of the Rhodizonate tests
in separate beakers and apply each to the carpet in separate
areas. The following results were observed:
-
The 15%
Acetic acid- no color change
-
The Sodium
Rhodizonate solution- slight yellowing but disappears.
-
The buffer
solution- no color change.
-
The 5% HCL
solution turned the area into the prettiest purple area.

Questions:
-
Has anyone
ever seen this phenomena associated with the lead test?
-
Could it be
the dye in the carpet?
-
Could it be a
cleaning agent or additive on the carpet?
-
Is there any
published data documenting this change with acids to dyes
coloration changes on other types of material?
Thanks for
your help in advance,

Pinfire
Pistol
Our lab
recently received for addition to our reference collection, a
.41 caliber pinfire pistol with 16 L&G and a right hand twist.
The only marking other than the engraving, is the number "2"
on the bottom strap in front of the trigger, under the barrel,
and two places on the locking lever. The pistol does not
appear to be a reproduction.

Any help in
identifying this firearm would be greatly appreciated.

Unusual
Cartridges
We
recently received some unusual ammunition with a case.
The cartridges are .40 S&W caliber with Winchester
headstamps. The bullets consisted of a copper cup
containing eight pellets in an epoxy-like substance.
Four #2 lead pellet were seated at the bottom of the jacket
with four #4 pellets on top of those. The #4 pellets
were either plated or made of an alloy. Neither pellet
type was found to be attracted to a magnet.


George Kass contacted me and said the cartridges may
be made by MagSafe in Casselberry, FL.
I can’t
find a real good picture on their webpage and the bullet
weight seems to be off by a few grains.
Here is a
link to info on the MagSafe ammo:
http://www.impactsites2000.com/site3/magsafe.htm
I shot one
into our water tank and it fragged also immediately. I
found the jacket pieces about two and a half feet down the
tank.
If anyone
knows of similar bullets made by anyone other than MagSafe
your feedback would be very helpful.
Thanks,
