Question about case deformation

[Ccamp1988]

Ill preface this by saying Im new to reloading, in fact Im still waiting on equipment. I have been doing a couple months worth of research in preparation though and had a question about some range brass I picked up. This is Norma brass for 270win. Were these deformations from a bad die, or maybe a weird chamber in someones rifle? It doesnt look like it from the picture but the deformations are pretty much identical. Just curious what may cause this?

Just because it has .270 head stamp doesn't mean the chamber it was fired in was a .270. I've used 270 brass to form wildcat brass. Just a guess.

looks like a poor chamber to me.

Thats what I was leaning towards. Just never seen anything like it.

While many of us have used range brass to varying degrees of success, as a new reloader, if possible, I would urge you to begin your reloading hobby with virgin cases.

As you become experienced in the reloading process you may want to salvage range brass for economic / supply reasons. If you do not to have to salvage range brass for the aforementioned reasons, it is best avoided.

There really is not enough information to go on. Do you know if these are once fired cases, new cases? What rifle was it shot from? Factory or re-barreled?

Looks like the rifle those came out of had gouges in the chamber shoulder.

Someone made ammo fit by running a drill bit into the neck area of the chamber? That's pretty ugly.

Look at the shoulder, several rings as in some kind of cartridge reforming.

Reloaded with unintended crimp, shoulder was caved in a bit. But still chambered so the person fired them to see if the brass would form again? Saw the deformity and pitched them.
