looks like the imprint of your feed ramp. Ive never seen that, but Im not experienced as much in large caliber function and failures

Clean your chamber shoulder. Something is in there.

I've had some weird designs from straggler pieces of trimmings from god knows where make their way in there and was cool to look at until I realized I was abusing brass.

You have the new 7-08 Laverne chamber.
Get a brush and light and get Laverne out of there.

 

[bobdog308]

Nope, actual I just discovered the rifle Chamber fractured on me! Brand new Ruger m77 hawkeye. I'm so sick of all this cheap crap lately. I spent $839 on this rifle. Chamber pics to follow.

What are your concerns?

The blackened mouth or the dent to the shoulders?

I have been shooting bolt action rifles Almost every day since I was 7 years old, not counting 10 years in the us army and never had an issue, but the last 4 years I have had 2 brand new rifles totally fail on me. Thanks to Chinese steel.

I have never heard of that happening on any new rifle, let alone a Ruger M77. That is not an over pressure situation, but could be someone at the plant over torqued the barrel. Or, you could be right on the cheap steel. Good luck getting it replaced. I wouldn't trust a re-barrel from the factory.

I literally got the rifle home, ran A few rounds through it, and bam.

Don't worry Ruger has excellent customer service.

 

[Member 5605]

That's a first.

Radical fracture. @Velzey you think an over torque?

That sucks.....,,

Looks like a metal shaving is stuck up in the neck of the chamber.

That's what it looks like to me, Very similar to the impressions made in cartridge brass when unburned powder sticks are left behind, then another round is fired.

 

[bobdog308]

No metal shavings, And that's a carbon steel barrel, proof rounds from Ruger are tested at twice the psi of the cartridge. So around 120,00 psi for a 7mm-08. This thing was either way over torqued or Ruger is now using recycled steel from China or elsewhere overseas. I doubt over torquing would even cause this bad of a failure after a few rounds. Just plain shoddy craftsmanship and Poor quality control in my opinion. Won't ever buy Ruger again. And this was a $900 rifle. Everything is crap nowadays that was once quality. Thanks Bush and Obama.

 

[Velzey]

Bore scope it, and I don't think an over torqued bbl would cause this.
And as for Ruger, they have the best customer service around. Call them up and tell them there is a problem. They will send you an RA number and fed ex label.

 

[bobdog308]

Called them, great service actually!

 

[elitejake]

Wow. That's a serous failure in any event. I don't have any direction to point for fault. But I'd say you at a min should be getting a whole new firearm. I don't think I'd trust the receiver after that. If it was over torqued did it impact the receiver? I don't think I'd take the chance.
