I did shoot the RBL-16s at clay targets and they performed very well both at skeet and sporting clays.
The ICD-16 was my primary gun in MT last year and my RBL-16 the backup gun.
I am taking the other half of the matched pair to Canada in three weeks. It's an ICD 28ga and is just as nice. I will have an RBL-28 as backup/rainy day gun.
