Can you use a sabot slug in moss berg 930?

You can use a sabot in any shotgun, as long as the barrel is not choked. If you have screw in chokes, you will want to use ONLY the Cylinder or CYL choke. Otherwise, you will need to look on the barrel to see what it is choked in. If you do not have screw chokes, unless it says CYLINDER or SLUG, it is probably choked. (It may say Improved, IM, Modified, Full, etc)
