They do make .410 slugs but if i were you i'd get the 20 gauge. Less recoil than the 12, more power to reach out and touch things than the .410. They do make the H&R Ultra Slug hunter in 20 Ga, that baby is a tack driver. If you want to shoot yotes and save the pelts i'd get a .223 or .243 Handi-Rifle by NEF. Very accurate, very reliable firearms.
