antse7en,
Just a thought ,
You say you are fastidious about cleaning and after care of your gun ?
Could you have possibly shot the gun whilst there was an oil residue in the barrel ?
This has been known to have caused detonation and wave pressures which can result in ring bulges in the barrel !
I have guns that were originally fixed choke which I have had Teagued and I am confident that the barrel wall thickness has been left with adequate thickness to accommodate the fitment of multichoke.
I have to say that you have been very unfortunate to have suffered such a catastrophic failure .
Please remember that your undamaged chokes can very easily be retrofitted to another set of barrels or even another gun.
