Welcome and welcome to the STW club. We even have a 7mm STW subforum here.
I like the Siroccos a lot and shoot them extensively. The one thing I'd caution you on is that at these velocities they are rather explosive at sub 300yds ranges. When I say explosive I mean hitting a coyote center mass broadside with them consistently cuts them literally in half.
At longer ranges they perform flawlessly with consistent controlled expansion.
I haven't shot anything bigger than deer with them but those deer I did shoot we had perfect performance on.
With the 30 cal 180's I killed one huge old boar with a high shoulder shot and got a complete pass through with the bullet not quite making it out buried up in the cartilage sheild on the off shoulder which was about 3" thick.
I have shot dozens of large boars with the Hornady interlock and interbond and most of the time they did exit even on the same shot just as a comparison for you. The wound tracks tough internally were very similar.
