I will try the sabot slugs; they should be going fast enough to do some damage at close range, rifling or not.
The buckshot would probably WORK fine for my purposes, possibly better than slugs. But (the BIG butt), for some reason buckshot isn't allowed for big game in CA. Riddle me that one. On second thought, don't even try to make sense of it. If you could, it would stand unique among our state gun/ammo regs.
