FBI Evidence Proves Oswald's Ammunition was not Capable of Sufficient Accuracy to Kill JFK

[John Lewis]

It may have hit something else first. A dent like that on fired brass is not uncommon, especially on relatively think brass such as the type used on 6.5mm ammo.

Mr. McAdams...errr...Lewis

Please explain to all of us exactly how a cartridge case could be dented in this fashion, especially one as relatively "think" as the Carcano.

Pointing out typo's - very mature. You'll notice that I did you the courtesy of not pointing out yours.

Cartridge cases get dented like this all the time. I got the impression that you were a shooter? If you were then you wouldn't be questioning that fact. They get dented when the empty case gets flung from the rifle by the ejector. The extractor drags it from the chamber by gripping its rim near its base. The case is dragged over the ejector by the rearward travel of the bolt causing the case to pivot away from the rifle using the extractor as the pivot point. If the bolt is moved rapidly this can impart a substantial spin to the case - the part farthest from the pivot point moving the fastest. The part farthest from the pivot point is the mouth - which also happens to be a rather thin piece of brass. If that hits something it can get dented. It's as simple as that. Brass can even be dented like that by hitting the part of the rifle receiver on its way out.

This is all very commonly understood stuff to anyone who is reasonably well acquainted with firearms.

Utter nonsense. I have tried this many times and, while it is possible to bend the edge of the cartridge mouth over, it is impossible to dent it in from the side, as the casing from the 6th floor was dented.

I suggest you make the most of your time here, as your type tends to get banned fairly quickly here.

Sorry but it is quite possible. I've seen it happen. If your argument is that it is impossible for a piece of thin brass which is hurtling through the air and rotating rapidly to be bent if it hits something hard then fair enough, that's your argument. People can make what they will of it and compare it to mine.

The other way in which damage like that could be sustained is via chambering it (the empty case) into a rifle. Brass is commonly damaged in similar ways if care is not taken. It tends to foul the locking lug recesses in the receiver.
