the range where you can place at least 3 pellets of #2 buckshot is your max. Use the same plates to range your slugs- the range where you can hit it 3 out of 4 tries is your maximum. In another words, a 20 ga slug will kill a deer much farther out than you can likely hit a deer.

A shotgun shooting a slug is also much more precise than a shotgun shooting buckshot.How accurate are rifled slugs?
The effective range of rifled slugs is considerably less than that of saboted loads. But most shots taken at woodland deer are within 100 yards. Using a rifled or full-bore slug is no disadvantage at this relatively close range, but only if you can place the slug where you want it.
