How many of you saw the test on TV last night where Gunsite did the shotgun test? I thought it was interesting as it gave some insight into how a 12 gauge will work for bear protection. They tested birdshot #7, slugs and buckshot. I have used buckshot on a grizzly and knew it worked, but was surprised at how the #7 at very close range stayed together, acted almost like a slug. At 25 yards the buck penetrated 3 typicial walls as did the slug, so for home defence the #7 is the way to go.
