Bulging Brass, new Rossi R92 .357

I have no faith in Braztech craftsmanship. Sorry, but just none. Google Taurus lawsuits if you have time, plenty of time. Same bathroom, just a different stall.

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.

That's some quality Khyber pass gunsmithing right there.
Is that thing new ?

I had bought it with the mind that it takes a special kind of negligence to mess up a 92. And I know full well that you get what you pay for, but for $500, you should be getting a better product. We will see what they say.

Let's say hypothetically this happened from wear in an older rifle. Would building up the area with TIG and reshaping be a good bet or rebarrel and call it done?

I would ask Tom Turnbull of Turnbull restorations if that is safe and if he will do it. If he does, it won't be cheap but it will be done right. :thumbsup:

Since it's hypothetical, I won't waste the man's time. Random early morning thoughts when I hurt too bad to lay down but it's too early to really start the day.

I know the feeling well. I don't think I have had a good nights sleep in the last 10 years. :sad20:

The cartridge headspaces on the rim of the case. The little "ditch" at 6 o'clock in the barrel is a feed ramp that is necessary to the design to insure reliable feeding. The bulge I am seeing at the bottom portion of the case is due to the chamber size. The bulge is not uniform all around the case because the case is not perfectly centered in the chamber. That is the nature of the design. What needs to be determined is,
1. Is the chamber within dimensional tolerance?
2. Is the feed ramp within acceptable range and not past the thicker part of the base of the case, known as the case head?

Any decent gunsmith should be able to check it for you. If either of these is out of tolerance, send it back for warranty repair.

Looks to me that someone filed a ramp into the chamber to correct a feeding problem. I would send it back.

I have owned numerous R92 rifles and never had a problem with bulges. I quit the R92 due to the difficulty in getting parts from the factory. Frankly, it is a 50/50 chance that you will get one with problems.

I would say get a Henry or Marlin. If you can find a pre-Taurus Rossi rifle, those were OK. Had a couple that worked perfectly.

Agree, knowing the diameter of the existing chamber relating to the cartridge dimensions would be a big help. The chamber is more than likely generous to accommodate for a lack of primary extraction. It's a lever gun.

I've seen better craftsmanship on Khybers :innocent0

I just looked at my wife's new Rossi 92. I don't have enough hands to hold it, a light, and get a pic, but the chamber does not look as third world as those pictures...at all.

I also poked around in my range bag to find the brass. I'm 99.9% sure I found it (the long scratch on the side of the brass from going through the loading gate, and faint extractor marks tell me it did not come out of a revolver), and there is not even a hint of that bulge. Now, it was Herter's .357 and, given the little bit of soot on the outside of the case, I'm guessing that it is either fairly light or has thick/stiff walls. The other ammo we shot that day was .38, and it was also fine.

So, I'm afraid for the OP that we can't say, "that's just how these rifles are" :sad20:

There was a long thread about some Glocks doing this to soft .40 brass (that was back when .40 was a thing).

Johnconlee · Mar 11, 2019

That doesn’t look normal to me and when it comes to warranty work the sooner the better.

So my chamber doesn't look nearly as rough as Mike's does, but then again I got spooked after about 50 rounds, he very may well have put many more through his.

My new Rossi 357 has a slight polished area in between the two extractor slots, but it doesn't extend any further into the chamber than the end of the slots. Very minor compared to these pictures.

I put approximately 170 rounds through mine. All were 357 except for 15 rounds of 38 SPL. My photos are at ~6X and 8X magnification, so maybe that is why it appears so rough? :shrug:

It does not look all that bad to the naked eye.

I can easily put the fired brass back into the chamber by hand, without forcing it. Does that mean anything? Probably not.

Do we try to contact Rossi or the place where we bought the rifle from regarding this concern?

I was able to rechamber fired brass as well to test fit. I had to apply a little bit of pressure and then set the extractor and throw the brass again to get it out.

I'm sure the magnification is making it look worse, it's an awkward photo to take clearly.

I suspect that Rossi may be having finishing problems and perhaps a metallurgy issue. The steel just looks really worn for such light use.

Today, I sent an email to KY Gun Co, where I bought the gun. I included some photos and a request as to how to proceed. I will pray for a satisfactory outcome.

re: bulging brass

Cornelius said:
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.

Your chamber seems to be cut a little on the generous side based on the obvious expansion above the case web. I would send it back to the manufacturer if I were you..............!

Return sent

I received a FedEx return label from "Repairs" in Miami, FL yesterday. I made a box to fit over the OEM box and sent my rifle back to them for repair. I'm now in wait-and-see mode.
