Zep,
I'm pretty sure that would wipe out a bear if it hit the bear where the bear needed to be hit, which would likely be easier to do under pressure with: a rifle. Like I said in the other post "We'll have to agree to disagree"
At least you have good sense when it comes to quotes.
How is the recoil with that BFR? Lets use a .44 Superblackhawk with 320gr cast loads at about 1300 for the baseline of comparison. That would only have about 1200.58 lbs of energy.
