Ok here is the deal. I work in the "delivery" business. And recently came basically face to face with a good size black bear. Head about 20" and had a azz about 36". So got me thinking of what caliber would be best for a black bear. MY OPTIONS ARE .45/.40/357/ other. Now i dont plan on huinting them or able to carry any kind of cannon. We;re talkin CC 6-10 rnds. So any thoughts?
