It's all here: https://www.benelliusa.com/support/faqWhich choke do you use for slugs or is it better to purchase a separate barrel for slugs?
No doubt... and if you do go to a rifled barrel & sabot slugs, the sabots can be considerably more expensive than standard rifled slugs.I've shot many a deer using an Improved cylinder choke. Do yourself a favor and shoot a few out of your shotgun before deciding on a dedicated barrel. You may be surprised at the accuracy. Also, smooth bore or rifled, be prepared to spend a few bucks on finding what shoots best in your shotgun.
