All shotguns even the same model like different ammo. You would have to try different slugs to see what your shotgun likes. I have a Remington 11-87 with the rifled/cantilever barrel, and I use LIGHTFIELD slugs, I took a few deer, and a NJ black bear with them last year. Remington has a habit of undersizing there slugs, also there is a habit that there slugs work good in there shotguns, try there buckhammer, copper solid, or ultra core-lokt
