Wierd Case

[Wineman]

I was at a CMP match and while searching during "Brass Call" I found the case on the left. It has dimensions of a 30-06 case at the head and shoulder. The ID is 0.309". The rim is slightly bent and there is a bright spot on the bottom of the rim. It is an HXP 78 and it still has the original primer in it. I have seen 308 in a 30-06 chamber do this but I do not know what you could shoot a 30-06 in and have it come out like this. A mystery to me. The one on the right is a normal HXP case fired in my M1.

Somebody put a 30-06 in something they should not have, it looks like to me.

That's what appears to me too. If the only thing on the line was M1s then...but it's been fired in a chamber longer and the same base size. What could that be?

[Wineman]

That's what I was puzzled by. It was not the same match so I have no idea what it was shot in. It was at the 200 yard line on a 1,000 yard range. There are many groups using the range. I do not have cartridges of the world so making a comparison is hard. Something the same size as the 30-06 but a third longer and still 30 caliber??? A barrel not installed properly or a chamber reamer out of control? Kind of like a Bigfoot sighting. Someone does this at home and then leaves it at the range to get people talking.

I'll bet it was fired in a 300 RUM. If you look at the cartridge drawings, the numbers come close enough, and the rifles are popular enough to explain the presence of one. The other parts of the recipe are uncaring or unknowing shooter and a pile of ammo. You guys look at the cartridge line drawings together and see.

Thanks, I will look in my Sierra book.

During brass police call I also found a strange spent case. A 5.56 fired in a 7.62X39 chamber.

[browningautorifle]

Well done that one!

Could that first case be a 30-06 fired in a Navy 7.62mm rifle, converted to a 7.62 by using the insert, and the insert has come out? With many years of range officer experience, I have found that mny people believe that"if it fits -shoot it".

[browningautorifle]

The 30 cal rifles were coverted using what appeared to be a separated casing. That is to say it's only half an inch. The front of the casing only. If they came out, the 7.62 would be 30 cal M2 in length. This is a 30 M2 that's wide open, therefore it's something longer than 30-06.
