Is that a bullet lying on your bench near the center of this photo?

I'm trying to figure out how that is involved in the development
process.

Could be a safety hazard if it accidentally got some juice flowing
through it. I'm impressively messy at times, but when stuff gets
powered up, it usually is very, very neat (especially expensive and/or
power stuff). Igor has the bulk of it relatively neatly placed on the
wood board, but there is enough clutter to be worrisome.


Best regards,

7.62x54R actually. Its a known length..so it makes a good reference
item, though its usually laid horizontally in the frame to make
comparison measurements easier.

The round also looks like a 30-40 Krag, or 6.5 Dutch, because of
foreshortening effect, but based on Iggies proclivities..Id have to
say the Russian round is more likely, and given the red primer
sealent..most likely East German..though it could be Slovak. I couldnt
blow up the photo large enough to read the head stamp code and tell
you which factory it came from

for torturing the cat." Gunner

Well, nowhere I have over 0.5 A flowing right now.


Looking at the image zoomed in, it *appears* that the primer is
indented, so it may be an expended one with a replacement bullet seated
in it to serve as a setup gauge for reloading dies.

Still not sure why it is there, however. :-)

Enjoy,
DoN.
