In this video they reduced charges until they stuck a bullet in the barrel. Then they fired 2 more further reduced loads. So now there are 3 bullets in the barrel.
The last step is to fire a full power round. I wouldn't have believed the cylinder didn't come apart, but the only damage was a bulged barrel.
