RE: Shotgun Slug vs. Rifle
Slugs are better than buckshot, a decent cal. rifle is better than a slug, and also something like a 270 Win., 280 Rem., 7mm-08 will have a lot less recoil than a slug.
Yes, a decent cal. rifle loaded with the "proper bullet weight" will easily kill faster than a slug... At least in my experience that's the way it's been...
