I know of someone who overloaded a CVA Bobcat with the GP 410(I won't give specifics). Did it more than once. Of course, he wasn't shooting this rifle from his shoulder. He built an apparatus from which todischarge it and did it as safely as such a test could be done in a field laboratory.He wanted to convince himself that the rifle was safe with the loads the manufacturer approves.

The nipple wasn't dislodged and the barrel wasn't bulged. His report left me convinced that there is nothing wrong with the quality of its Spanish steel.Seemshe got a very good one, built plenty strong enough.

Even so, I suppose there can still be be problem with any particular rifle from any manufacture from defects in workmanship orinsufficient quality control. This is why I always recommend starting with lighter loads (just like with cartridge reloading) and working higherwhen breaking ina new ML rifle. Just makes sense. If thereis aproblem, its at least possible to detect it before dropping 3 pellets.

I really do think that most problems result from lack of respect of the dangers. Specifically, the failure to use a safe loading regimen. I would wager that most burst barrels are the result of leaving a ramrod in the barrel upon discharge.
