What you are looking at is the barrel chamber. There is no separate feed ramp on the 1892 style rifle. When done properly, the edge of the chamber is chamfered lightly and the cutouts are made for the extractor and ejector. If you had a headspace problem, the brass would be expanded around the entire case. As it is, someone did a sloppy job of either cutting the chamber or chamfering the mouth.

Sorry, but you need to return it and they'll rebarrel it.

This is what I could get a picture of on my rifle. All the debris in the last picture is lint from a tissue. The little “ditch” can be seen at the top of the feed ramp. I think that is the source of the crescent deformation in most of my brass. Note my 38 SPL and the 357 Fiocchi brass did not have the deformation.

Looks like a lot of material has been removed from the chamber and could extend in to an area not supported by the head of the case. Cut up a fired case and measure it to see if it is thinning. If you don't have any babbitt or cerro material to make a cast, you can melt powdered yellow sulfur from the rx and use that if your handy. Just don't do it in the house or breathe that mess in unnecessarily.
A sulfur cast will be brittle but if done right will show abnormalities. Warming the dried parts with a hair dryer is a +

Thanks for your input, I dread having to send it back but I supposed it'll have to go. DANG IT!

I am going to cry excessive headspace. What caught my attention is the way the rim is deformed forward in the first pic of the OP.
357 Mag headspaces on the rim. The second pic in the OP shows what appears to be an extractor mark in the extractor groove. It coincides with the rim deformation. In the first pic you can see a section of the rim pushed forward. What may be occurring is the bolt side of the extractor is supporting the rim while the remainder of the rim is pushed back by case thrust during firing.

If it was pressure bulge at the feed ramp we would probably see impressions of the two square cut sections in that part of the barrel. Just my .02

Yeah, it's kinda hard to show in photos, but the case appears to be pressure-formed to a bad chamber. I'm bummed. Shoots great too.

Don't risk it. Rossi should make this right. Do it now and they should cover the full cost. I waited too long to send a rifle back to Chiappa and they made me eat the shipping.

I just realized that the 38spl and Fiocchi may not have had enough pressure to form the case or cause a problem. The federal and surprisingly the Geco can be pretty stout. Calling them Monday, I'll fill you in.
