Yeah I read the spray is safer than a gun because a bear can still charge after it’s been shot while if it gets pepper spray in the face it freaks out and runs away.
In your dreams.
Alaska guides usually protect their clients with a .338 Win Mag, .300 Win Mag or such. I believe Alaska mandates minimum rounds for guides to protect their clients.
The EPA regulates pepper spray, and the best stuff is not approved for use on bears. You can’t make this stuff up!
