I have no experience with the 7 rum but have shot the 7rm a lot.- the 160 accubond is the best overall bullet i have found.
The scirocco 150 has great terminal ballistics but it is (in my
not so accurate and penetrates far less than the accubond.
I´d say the 162 a max is too soft if a shot at shorter ranges is the case.
No experience with the 175 SMk or 180 berger.
