I am going to carry my 12 ga shotgun in the woods until I decide if I want to switch to a rifle. Whats the deepest penetrating most effective 3 inch slug for a chargin grizzly bear? http://www.brennekeusa.com/cms/blackmagic.html What happens if you use a rifled slug in a smooth bore barrel? I like the remmington accutip but was not sure how accuret it would be in a smoothbore mossberg 590. http://www.remington.com/products/ammunition/shotshells/slugs/premier-accutip-bonded-sabot-slug.aspx Wanna kill these ads?
