I have a brand new Benelli M4 S 90 Combat Shotgun. I am looking for a place to practice and “PATTERN” the gun. I intend to use steel shot and slugs. I have learned that most gun clubs do not allow the use of steel shot or slugs. Can some one tell me where I can shoot this weapon without a lot of hassle? I live in Potomac, Maryland and am will ing to drive a reasonable distance to practice. Also would like to shoot my AR-15s.
