Only shotgun slugs can be used here in Illlinois so buckshot isnt an option for us. However, I've talked and chatted with folks from different states that have used it and it sounds like about 40 yards is MAX with even the best grouping buckshot and chokes.

As mentioned above, their are MUCH better options to use than Buckshot. If I were limited to shotgun only (if I couldn't use my muzzleloader) I would most certainly opt for a SLUG... they are awesomely devastating to any deer they strike!
