The SSTs have the following trajectory which you could just look up for yourself on the Hornady site.
12 gauge
+2.4" @ 50 yard (this means the slug is rising from a properly held barrel)
+2.7" @ 100
0" @ 150
-6.7" @ 200
20 gauge
+ 2.5" @ 50
+ 3.3" @ 100
0" @ 150
-8.2" @ 200
Nikon spot on is a ballistics calculator specifically for the Nikon scope. You enter all your load info, then it calculates your drop chart. I have found their system to be pretty close to 400 yards on my .30-06. and good on my 12 ga Mossberg 695 slug gun to 150 yards. Of course I still recommend shooting at the distances that you expect to shoot.... But I've found that program to be O.K. at the ranges I've used it at....
