Were you already sighted in for 100 yards? You are not trying to shoot a mosquito off their back, if you are a vitals shooter you have a lot of room up and down to hit the animal. I would lean towards the maximum point blank range, I have started doing this with every gun. You sight in so that you get the most range based on the vitals of the animal. If the animal is a deer you have an 8in vertical range for the vitals, even on a fawn. To give myself some play I drop that down to 6in. I then sight in so that the bullet will impact no more than 3in above of below the crosshair and then determine my maximum range. You can pull this down to 2in for varmints or 1in for things like rabbits, but the idea is that you just need to know that your shot will not be over that max range and line up on the center of the vitals. It is amazing what sort of ranges you would still have a kill shot with cartridges normally considered "short range" and "rainbow trajectory". This is a little tougher with a shotgun as you do not know the details of the bullet as well as with rifle bullets and reloading. You can use the ballistics table to get an idea though, the Hornady 300gr SST sighted in for 150 yards will be under 3in high all the way back to the muzzle, so a 100 yard zero would be even flatter than that, totally acceptable for your situation but still allowing for that long shot if it presented itself.
