Nice one Rev bullet comparison too! I'm shooting the SST 139 gr. they seem to hold together better than the Interlocks!
I haven't loaded the SST, but the Interlocks seem to do well on game. Maybe it just wasn't up to the test medium - tightly packed dry newspaper. I have that bullet in front of me right now and you can still see pieces of the paper in it. That inexpensive Prvi Grom came out exactly as you see it in the picture.
