After a lot of reading and research in my opinion S & B have been replaced by the FFP march 5-40 and Khales 6-24. Both if these scopes have or are coming out with a MSR/ACR. I know this might ruffle some feathers but please give your insight on which is best and if there is another that is better please explain. Please keep in mind this is for a DTA 308, 300wm, 260 and 338.
