I'm getting ready to go on a boar hunt. I've seen pics of boars from this area and they look like tough dudes. I'm taking a Marlin Guide Gun (.45-70) and will be shooting Buffalo Bore bullets. I'm also taking an Ithaca Deerslayer and am trying to figure out what slugs to buy. Someone makes an all-copper slug and I was thinking that this might be the way to go. Any opinions?
