First -skip the subsonics. You're not smoking sentries before the assault team moves in. Super sonics will be fine without ear pro in the 300BO in your house and have MUCH better terminal ballistics.
I read great things about some of the 110 bullet offerings out there. Some with near 100% fragmentation specs and nice short penetration- impressive. I can also appreciate the added usable range the supers would give me that the subs can't match over about 50 yards if the fight ends up outside at all.
I have a friend that was a police sharpshooter and he said for non barrier urban sniping type targets they used Hornady 110 grain Tap Urban in .308. He shared a story where they had a hostage taker and the only shot they had was at his face. He said that bullet was like a tiny grenade went off in his head.
