Thisguy I know in Alaska has a cabin on an island. While driving his boat around one day he decided to go to the cabin to cut some firewood and tidy up a bit. While he was cutting wood he glanced back down to the beach a saw a brown bear walking the shoreline apporching his boat. Just then he and the bearmade eye contact and the bear started on a full sprint toward him. Well since this was an unscheduled trip to the cabin he had no key to actually get inside the cabin so he reacted andstarted running, but the bear was catching him quickly! Hejumped in full sprintin desperation on to a 55 gallon barrel and then leaped for the roof of the cabin. Just as he was almost up on the roof of the cabin the bear grabbed his leg and started to pull it just like I am pulling your leg right now.

Back on topic, the biggest thing I've ever seen killed with a 30-30 is a deer.
