with all the talk about coyote calibers......has anyone tried a .410 slug on them??? i think that would work well at close to medium ranges. do they make sabot slugs for rifled 410 barrels...i can see that being the nonrifle solution to coyotes. 3" single shot rifled .410...maybe 70yards max? what do you guys think?.............do they even make rifled .410 barrels?
