Shooting BOOMERS in a gun not proofed for boomers????
In total honesty, this is simply "NOT" apt to produce a bulge at the 18" point. In fact it is most unlikely to produce any kind of an "Instant" catastrophic Failure at all. Bulges & Bursts are nearly Always attributable to some cause other than an overloaded shell. Understand this is "NOT" meant as condoning the use of overloaded shells, which can certainly accelerate the wear & tear on the gun, they just aren't apt to "Blow it Up".
Understand this is in reference to normal Heavy loads, not meant to include some foolish reloading error as dumping say 47 grains of Red Dot or other quick powder behind a 1˝oz shot charge. This might just ventilate the chamber, but would still not be likely to produce that 18" bulge.
