Ever have a round sound bad, or like it was a dud, only to open the bolt and find a spent case? And then without thinking, you fire another round at the target, only to have it go a stray and not even hit the target. No problem, must have been a bad bullet, after all, every mfg'r puts them in the box. Most of the rest of the rounds score fair, but not like the last lot and the final score was sort of down. Well here's the rest of the story. The action was cleaned, and there were no empty cases around to chamber, so it had to be a live round. The round likely had little to no powder, and failed to make it out of the barrel. What one should have been done, would be to run a cleaning rod thru the barrel to see if the bullet did indeed leave the bore and it was just a bad bullet that didn't even hit the target. Instead, another round was chambered and it collided with the stuck bullet and cause a bulge in the bore, pushing both out of the barrel in an unknown direction. End result, was a badly damaged barrel which amounted to a bad day at the office. Word of warning, if a round sounds like it may have been low on powder, and failed to show up on the target, take the time to check the bore. You just might save yourself some grief and the cost of installing a new barrel.
