My grandfather left me a Remington 11-87SP a while back. He always told me that it was a Sabot rifled barrel and healways used sabot slugs in the gun. After a wet Michigan opener, I decided to really clean and oil the gun as this is the first time I carried the gun. Upon inspection, the barrel is a 21" smooth bore barrel with a rifled choke and rifle sights.Not a rifled barrel. Obviously this gives me more optionsandchances to use the gunifI purchase different chokes. I realize all guns like and dislike different ammo and I need to get to the range to test, but what type of accuracy and distance can you generally excpect with a rifled choke vs a rifled barrel?

Thanks in advance for the information.
