I have a Mossberg 9200 and have been shooting KO Sabot slugs. They work great but I can no longer buy them. It seems that they no longer make KO sabot slugs and I'm trying to find something else. I learned the hard way that the Mossberg gun does not shoot just any sabot type slug. Can someone tell me what type of slug to use. Will Federal Sabot slugs shoot without tumbling?
