Bulging Brass, new Rossi R92 .357

So I have searched the forum for a previous thread to no avail.

I recently bought my first Rossi R92, my first 92-style lever action rifle.

At the range, I noticed a slight case deformation near the base of every single case after they were thrown. I ejected a couple gingerly to make sure it wasn't impact damage.

I just want to confirm that this is normal forming to the chamber for this style action/gun before I use it any further. I used both federal and Geco brass and the bulge is identical on all of them, so I don't think it was an ammo quality issue.

I may just be inexperienced with this rifle and overreacting, but I thought since I joined this group I should ask.


Appreciate any help.

I saw your question in the other thread. I posted my reply to you below.

I'm having difficulty seeing the bulge you are describing. Maybe I'm looking for the wrong thing?

Thanks for your response,

Maybe bulging is the wrong word. Deformation is probably more accurate, about .5cm above the rim. You can see it best I suppose in the top photo.

I just saw your response on the other post. That's the exact issue I'm referring to. I have to think it's just forming to the feed ramp and I'm just not used to seeing it so pronounced.

Yes, based on the shape and consistent position, I think it is from the feed ramp.

Send it back, the chamber is not cut correctly or they over chamferred it.

So you think that Mike and I both have defective rifles?

It wouldn't surprise me as Rossi's quality has been on the wane. The case in an 1892 style rifle should be fully supported and should not bulge on firing.

No doubt it is a cheap lever, but as I look more closely, there is a defined feed ramp that aligns perfectly with the deformation. the case is not intended to be fully supported in Rossi's 92 offering it would seem. take a look and let me know.

Also, I tried to no avail to post this right-side-up. But you get the point
