hey guys what slugs should i be using with my 12 gauge mossberg 500? I've got a 24 inch slug barrel but im pretty sure its not rifled. I need to be using 3inch slugs, all help is appreciated thanks!
Back in the 60's BRI (Ballistic Research Institute) of California did extensive research with their slugs using the Mossberg 500. It is now knownas the Winchester BRI., but it's a Sabot for Rifled Barrels.
