The tone here seems to be that, if it's an ideal shot, anything will work...and that on non ideal shots, 00 is easily foiled. I don't have much faith in 00, or buckshot in general. I know it works just fine (on ideal shots) but there's less ideal shots nowadays so it seems to me that slugs are your ultimate versatility as far as a SG goes.
Yeah, I have 00 Buck in the gun. The first two rounds. After that is whole lotta slugs. It's hard to not have confidence in slugs.
