Free: Contests & Raffles.
I grew up hunting on an Air Force base that was divided into sections based on weapon. Rifle, Shotgun, and archery based on proximity to missile sites, runways, and housing, etc. The shotgun and archery areas were the best. Buckshot was prohibited. I've killed 30+ deer with rifled slugs (lots of wild boar, too). They take some practice at extended range, but they're close in trajectory to a heavy blackpowder load. I've killed deer from 25yds to 130. Beyond 100 I would not recommend without a lot of practice. I think at the yardage you mentioned, you'd be fine either way, but the slug will definitely have more immediate effect. Slugs hit HARD. Oh, a word of warning. When you go to the range to sight in... Rifled slugs kick harder than most things you've ever shot. "They kill on both ends!"Wile E.
