I don't know how I missed this but here is the patch that was on this uniform (Photo 1 & 2).  How do I know this will I just so happen to have photographs (Photo 3 thru 8) of one of his other uniform tops (Noland) with this patch sewn on the right shoulder which I missed while going through my reference material the first time around.  What is a little strange about this uniform is the name tape and USN tape appear to have been replaced.  It might have originally had the same type of tapes with the wider zig-zag sewing perimeters.  So if you can find this patch you can restore this uniform however this patch will be difficult to locate as they are scarce.   This was never UDT but during the Vietnam War UDT did work with IUWG.  

Definitely a possibility, asked an Army friend and he hadn't recognized it. I had found possibly the same site also. It is definitely a good copy if it is, it even has the surplus smell to it like all my other stuff that has tags. 

My guess would be that the bullet was slowed down enough to had penatrated this case and stopped before traveling all the way through.  Perhaps it hit a enbloc clip for a M1 Garand that slowed it's travel. Neat round, probably has an interesting story.

Unfortunately, it appears to be permanently closed....  

Beautiful patch.  

Thank you otter42, I think it's 30/06 but not sure. The headstamp doesn't say & I don't know enough to know from measurements. Your pic is awesome. I don't think it looks like a dummy round due to the dent and bent in metal vs cut away metal.

Thanks for the insight and info... much appreciated.  

Thank you eagle mtn, That scenario would explain the dents in the back side of the casing. But would the 30/06(maybe) have been belted in Vietnam? I also found some of these rounds in M1 clips (I think), but they were in a different box. Were M1's still being used in Vietnam? I'll see if the dent lines up with the lip of the clip.

Nope, it was just a image showing the face of it.

There is evidently some way of washing them as I have a top and pants in the woodland version that i got from two different trift stores that still have the lining but no charcoal left. The top was took to a cleaner at some point because there's a tag from them pinned to it. I've also seen an od top the same way. I think I remember seeing someone somewhere on this forum saying that you could vacuum a lot of it out.
