my 18.5 mossy barrel is CB
whats a bear banger? that sounds handy.
Essentially a 12guage flashbang. Legal in Canada (before you ask), I picked up a couple packs from our local Canadian Tire.
As for "zombie protection" I'll stick with 00 buck - tried, tested, and proven, against "remote rest stop zombies" the world over.
Found this vid of a guy testing bear bangers. Keep in mind, in person, they are MUCH louder - camera mic's don't really pick up on the level of noise.
