Single seven Kaboom

Was the ammo jacketed? Its not common any more but a jacket may have came off in the barrel leaving an obstrution.

It was jacketed. I've never heard of that. I'll have to do some reading.

And I'm now going to pull down the one box of factory ammo I haven't shot. I see an ammo recall in the future.

Wow! Be glad you were not damaged. As for this not being your month with Rugers,a lot of brand new Smith&Wesson revolvers are being returned to the mother ship lately for quality control issues. I sent a brand new performance center back in November for a couple issues that should have been corrected upon final inspection if there is still such a thing.

Tell me about it. The charger I sent back had areas on the receiver that showed the metal in the white, the stock had noticeable tearout from cutting and the bolt had rust on it. How did that pass??? Even if the rust happened after shipping I wouldn't think that would pass. I know they make a lot of guns and some will be clunkers, just had some bad luck this go round!
Oh well. First world problems hard at work again. I'm happy I'm unharmed and have enough expendable income to afford such luxuries. We are all blessed here.

I got my seven and a half inch single 7 back from Ruger for the loading gate and chambering the issues mentioned elsewhere, and they appear to have fixed it.I found its chambers to be tighter than the Buckeye 32 h&r I had reamed to 327, and also tighter than my GP-100 in 327.However,it will chamber factory ammunition. In his extensive article in the current Handloader, about this revolver,Bryan Pearce is critical of the Ruger engineering regarding the chambering problem several of us have mentioned on this site. Ruger did not challenge me in any way about returning the gun, and paid the shipping both ways with no charge for the repair. I probably will go ahead and shoot mine, but I feel that based on what I am reading about the returns to Ruger that they are effectively doing a recall, if not in name, then in fact.

Your experience makes me suspicious of the barrel, thinking that an overpressure round would rupture the cylinder before the barrel,but I have not seen enough guns damaged to really know that that is the case. My bigger concern is that if there are enough problems with this particular model that Ruger will respond as it did with 357 Maximum, by ending production and refusing to return models submitted to them for repair.

Hmmm that makes me want to send mine in now instead of later. I would want mine back.
Waited far to long to finally get one.

Sure glad mine is the 8 shot Blackhawk, I like the extra weight, others might not.

Were these light bullets? 100-grains or lighter.
I have given a bit of thought to jacket strength and high pressure.
The ammunition manufacturers and the gunwriterstend to emphasize high velocity when they shouldfocus on heavy bullets at moderate velocity.

[CJR]

Typically for overpressures, the cylinders/barrels let go where the pressures are highest; i.e. starting at the cylinders and going forward. When the barrels start splitting at the muzzle, it typically indicates bad metallurgy or heat-treat. Many barrels are batch heat-treated and the heat-treats can vary. Some barrel mfgrs. hardness test the barrels in several spots to insure proper heat-treat which is $$$$$$. As a result of the $$$$, hardness testing on multiple spots of a barrel is not done.

Glad to hear you're alright. Guns can always be replaced; our hands can't be.

Best regards,

Glad you weren't hurt - that's the important thing . . .

My first thought would have been "squib" but if they all went off fine and the casings wee tightly wedged - sort of looks like ammo. We can all "arm chair quarterback" this one and be way off. It will be interesting to see how this shakes out and what Ruger says about it. At least you stopped shooting it and caught it when you got home. Keep us posted please as it will be interesting to see what is determined on it. Not fun to have to go through it but at least you are in one piece. Good luck with it!

100 grainers

When I get home I'll post the lot number just in case. I was thinking that it was metallurgy as well. As others have pointed out if it's over pressure it starts the kaboom earlier.

As for the shells sticking that was because of the little jagged piece of metal sticking out and preventing the ejection rid from moving. Once I calmed down and but and inspected the gun carefully I found that to be the reason. Also thinking back to the range where I pulled the cylinder the brass fell out with a few shakes.

hoo-chee-mama glad you are all rite not hurt

[9.3X62AL]

23, I don't fault you a bit for being rattled during and after the occurrence. Such a thing would have scared the fantods outta me. It does seem that the ammunition may not be at fault if the fired brass shook loose in the manner you describe. Just a guess, as a hobbyist--I haven't risen to the ranks of Propeller Hat Wearer yet.

Again, very glad that you were not injured by this anomaly.

[theperfessor]

That barrel isn't bulged from overpressure. That looks like a brittle failure that started at a roll mark line. Bad metallurgy and heat treating most likely.

[lefty o]

i agree with the above, appears to be overly hardened metal.

[FLHTC]

Sure am glad I bought the Blackhawk. Was this posted on any of the Ruger forums? I can only speculate what caused the problem but a short duration pressure spike will crack steel. It doesn't have to be overly hard to crack. Artillery shell fragments have clean cracks and they aren't hard.

[wrench man]

Maybe it a good thing mine spits out the base pin like it's supposed to?, I can keep an eye on the bottom of the barrel!?, I too have a whole pile of the Federal AE, in fact that's all I have, 85 and 100grn.

Not posted anywhere but here.

If the cases won't eject, either VERY rough chambers or WAY high ammo pressure.

Ruptured barrel points to high pressure. I think Fed wants to know about this ASAP.
Save that box of ammo, they need the lot numbers.

New gun and new ammo will be coming, no doubt. Good you are OK.
