“The can should be located behind the target, similar to where the brain is located on a bear.”
I must have scanned over where that location is in the article.
Based on real world bear attacks, you don’t aim for the brain. Odds of killing the bear aren’t all that great anyways. But even a 9mm has an excellent record of getting bears to break off an attack.
Maybe the unfamiliar noise or maybe the unexpected sharp pain in a muscle? Don’t know, but getting a HIT in on the bear is probably more important than trying to get a brain shot.
