I am sorry my friend but I know of two people who have killed black bears with buckshot and one who killed a bull moose with buckshot. The moose was shot at 45 yards with an 3 1/2" 18 pellet load of 00, it droped like a rock.

One of the bears was over 500 lbs. and was killed with a 3" shell of 00. The other bear was around 350-400 lbs. and was droped with a federal 3 1/2" 00 shell. I will try to get a picture of one of the bears for you. Now if you think tose buckshot loads are bad mine has around 1/4th more power and penetration capacity than those. I'm just stating you the facts, you say that such big game animals are not killable with buckshot. The only problem is that the bears and others are not aware of the rule.

From Squirrel to Elephant, the Shotgun is your gun.
