Can unrifled slugs be fired in a Benelli M2 26" barrell shotgun safely, and with which chokes?

Question

I wonder if the slugs would be safe with the interchangeable chokes.

Answer 1

Yes, rifled slugs are designed to be shot through a smooth bore. Only Saboted slugs are designed to be fired through rifled barrels.

You would certainly never want to fire a slug through a full choke.

Don't forget what they say about slugs: They hurt on both ends. The recoil is brutal.

Answer 2

The best chokes for slugs is open and Improved Cylinder.  If you want longer range shots they do make rifled chokes too.  However I would suggest spending the extra few cents and getting rifled slugs.  Why?  Because if you want to use it for self defense too then you can fire a rifled slug and buck shot back to back without sacrificing accuracy or wear and tear on the choke rifling.  

I know that is what a lot of peace officers use.  But with 18-20 inch barrels.  

Personally I made a good shot on a wild boar using a Mossberg 870 pump shotgun and rifled slugs.  Dropped him like a sack of bricks at over 75 yards.
