No one should ever open a classic shotgun choke. For one you are only the "temporary" owner and you'll ruin the shotgun for the next buyer. If you can't change the shot pattern with spreader loads or Polywad double-wides or just let the bird go out further, like I do, buy another shotgun with the chokes you desire. If you're still not happy, buy a shotgun with screw in chokes and leave the remaining few untouched classics alone!
