I know everybody loves these threads, but it's a sincere question.
I have watched numerous charges, been around bears, read many accounts of mauling etc... so tell me if I have this wrong but it seems to me that most bear attacks occur with little or no warning (2 seconds or less) and in many if not most cases the person is on the ground before they can make sense of what is happening.
I keep reading articles on the subject making the claim that rifles are preferable so long as they are at hand, but I have to question the logic if a large enough percentage of attacks happen without sufficient warning to prevent contact.
If I'm on the ground being worked over I am going to have great difficulty effectively keeping hold of a rifle let alone successfully using it (and that's assuming it's a shorter carbine like the Marlin Guide Gun).
So are my assumptions wrong? What does the typical (although extraordinarily rare) encounter look like? What's your guess at the split between encounters with more or less time than sufficient to field a firearm before contact?
