A Friend’s Gun Exploded Today w/ RST Shell

[Craig Budgeon]

Drew, here it goes for the last time on this subject, look at the pictures of the explosions you provided. None of your explosions show a pattern and most of your explosions extend for an extended length of the bore. The W. Richards in question has the explosion begin about 6" from the breech is perpendicular to bore and follows the circumference of the barrel to the soldiered joint and ends with no further apparent collateral damage to the beyond the 2" exploded area. Axial shaft is my term, so far the Brits have not adopted it. Drew what recommendations do you want? Are you asking about a 410 ga. or an 8 ga. or something in between, Whitworth steel or wrought steel, RST loads or somebodies unknown handloads, your mint Parker or a used up Crescent Arms double. Wonder why opinions might differ?

Dang...I must have accidentally logged onto Doublegunshop!

For the record...I never disagreed with anyone, but just merely wanted to understand how Mr. Budgeon inferred those measurements.

I suppose I should have stayed at a Holiday Inn Express last night.

I'm out.

Errr, ah, you musta meant doublegunshop.com...

And your response to such a nightmare is a wise one.

Nice collection of wall thickness numbers here

OK. Parker Titanic steel and post-WWI Vulcan steel were AISI 1030 with a tensile strength of 75,000. Your MWT numbers for a 12g?

I know I would have the remaining RSTs in that opened box tested, at least to eliminate that variable.

Craig, I'm sure you know what you're saying, so I apologize if I'm a little dense. Axial, meaning parallel to an axis, still doesn't tell me which part you're referring to. In the end, it doesn't matter, as I assume you are just referring to 'a part' to scale the barrel wall thickness.
As someone, maybe Drew, said, wouldn't it be great if the original poster just measured the wall.
All that aside, I still believe the failure is due to an obstruction, and a 6500psi cartridge isn't going to burst that barrel by pressure alone.
