Take your pick. Just about anything will work at those ranges, from pistols to any centerfire cartridge I can think of. Which one can you afford to practice with the most? Shots like that are apt to be quick so practice will make a huge difference on whether you get the shot in a timely fashion or watch the deer walk away in the brush. Don't leave out a shotgun with good slugs and a slug barrel. Perfect environment for the serious knockdown power of a slug, IMHO.

Never underestimate your ability to overestimate your ability.
