I have not heard much about the Brenneke slugs. I did see them. I think they were the K.O slugs. They were not sabots though. I thought you couldn't shoot non-sabot slugs out of a rifled barrel. The remingtons are not sabots then either? There is so many choices out there. Im not sure yet what scope I am going to get. Once I get that figured out then I will start figuring out what slugs to get.
