IIRC it's really the Critical Defense ammo with a different colored insert and some VERY clever packaging. So, it'll work quite well as a carry load but IMO the bullet weight might be a bit light for a bear. Personally, I'll admit that I fell for the marketing and purchased a box of the 40 and 45 caliber. I really should know better at my age but it really is a superb bit of marketing and it wasn't hugely expensive.
