SST's are good bullets that perform well on deer sized animals and they shoot very good but just because they are a interlock bullet dont be suprised to see core jacket seperation. In the last two deer I shot with SST's in my 280 using 154gr. SST's I have had core jacket seperation. The wound channel was very impressive and the jacket mushroomed perfectly but there was no core to be found, they did there job but if I was to shoot anything bigger than a deer I woold choose the Hornady Interbond.
