You'll be fine at 100 yards, but be careful. My smoothbore shoots them 2" left of POA at 50 yards and about 4" left of POA at 100 yards. It would be helpful for you to shoot it at 100 yards just to be sure of your POI. I ended up with a 90 yard shot once where I didn't think I had anything much past 50. Sometimes a perfect gap opens up.
