It ain't like the regular Interlock. I blew one up on a 100 yard lung shot at started a 2650 on a 100 pound doe last year. Its a varmint bullet to me.
Pick a better bullet for breaking bone.
I tend to disagree, the SST's I"ve shot were too hard on hides to be even a varmint bullet.
Expect separation and fragmentation if you use them!
