Power last post nailed it the SST is similar to a Nosler BT and IB is similar to the Nosler Accubond.

As to how the SST perform much the same to the nosler BT and either one is my choice when hunting deer or lopers. They both are explosive style bullets but work dandy to drop a deer in its tracks. IME the accuracy between the 2 is very similar, however in my 7 rem mag the SST has produced a slight edge over the NBT in that department.

I can't compare the IB and Accubond yet as I haven't tried either, but plan to change that this year
