I don't know much about the Scirocco's or the new Scirocco II, so I can't help yoou there, but if you don't already have the bullets I'd try the 100 grain Barnes Tipped TSX. I loaded some up for my 257 Wby (Rem 700 LSS) with IMR-7828 and the accuracy is impressive. The TSX will perform every bit as well as the Scirocco on game, and probably better. I chose the TTSX to start for two reasons, it's all copper so there will be no lead bullet frag in any deer I shoot with it. The TSX will also stand up to the velocity of the 257 Wby for close-up shots where other bullet blow up and/or shed all their weight and penetrate poorly, but will still perform great out to very long ranges.
Since the range I shoot at was a muddy swamp out by the berm, these groups were shot at 95 yards.
