Dave www.davewilson.cc 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 Gunner "Pax Americana is a philosophy. Hardly an empire. Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules. Think of it as having your older brother knock the **** out of you 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. -- Email: | Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |
