I picked up a couple of dummy practice rounds for the M1icon Garand the other day. The shinier of the two has got a headstamp of FA 53 and the other is stamped FA 56.

There seems to be a solid plug at the base of the primer socket, and there's some sort of weight inside the cartridge. (one is loose and shakes a bit) Sorry the pics are so bad.





I found a photo of some similar dummy rounds on Flickr, but they are silver in color and are drilled with holes in the sides of the cases...but if you look at the last en bloc photo, they seem to have primers (or fake primers) installed in them.





I was just wondering if anyone here knew much about how they were made and how they were used. I'm curious to know the purpose of the dimpled cases- was that just a visual cue as to the fact these are dummy rounds?

Thanks in advance for any info.
