I Just ordered my benelli but have previously shot remington 870's and 1187's, ithacas and what not ( too many to list) but never a 912 ( made by franchi right?) but in all the other shotguns i have shot there all smoothbore barrels, so find out if you have a smoothbore barrel or rifled first, then if you have a smoothbore you should get rifled slugs and for shooting them i have always used an Improved Cylinder choke. Hope this helped maybe get another opinion on it as well just to be sure!
