I usually just have some slugs in the pocket for easy access, but if a bear were to come i would just fire the bird shot for a warning in the air, then at him if he didnt piss off then i throw a few slugs in and if he continues to come closer hes gunna regret it, but i rarely go walking around out there lookin for grouse cause there are so darn many of them by the roads, most the time when im out of the vehicle hunting i got my 30.06 instead of my shotty.
