I was at an estate auction over the weekend and in one of the $1 boxes of stuff I bought there where some large unfired shell casings. They have a 30mm opening are 173mm long have written on the side base 30MM 28108674 MMT-2-12-74. On the base it is stamped HM. Now if I am reading the marks I am assuming that the MMT number is the manufacturing date of Feb 12 1974. I know the specs for a GAU 8 is the same as this one but I believe the A10 came out a few years after this. Is there anything else that would use this casing? Could it be a pre production run for the GAU 8?

Any way to get specs to make or purchase a realistic "dummy" projectile to fit on the case? Any way to know what the proper projectile for this case would be? Stout but manageable, That line gave me a pretty good laugh, I bet the following line would be after walking back the 30 feet that the rifle threw me... |
