I've got all four and am eagerly awaiting the .410-bore. I've shot my RBL-28 very little, but the others quite a bit and the RBL-16 many thousand of rounds, mostly at Skeet, but also hunting. It is becoming my go to bird gun. I took a bad fall out in the Channeled Scablands with my RBL-16. I was well cushioned by heavy grass, but the RBL found some scabrock. A couple of gouges up near the head of the stock and some scratches on the barrels. I'm reasonably sure that had I been carrying one of my vintage doubles I'd have had a serious dent.
