I've shot quite a few of the 123gr SSTs in my SKS and 7.62x39 AR.
They shot 1.1" 5 shot groups at 100 yards in the AR.
They worked great on pigs and pretty good on deer.
They are a slightly tougher bullet and hold together well.
They make nice holes without exploding and destroying too much.
I have not tried the Fusions so I can't give a comparison.
