I've killed several black bears with the ABs and Sciroccos. I have never recovered a Scirocco. I did recover a 225 AB from a 338 WM on a close up bear shot at 12 yards. I wouldn't hesitate to use either.
My 300 RUM loves the 180 Scirocco with H1000, Retumbo, and Re25. It loves the 200 AB with Re25 and Retumbo. I killed several bears with shoulder shots at close range with the 180 Scirocco.
Here is my observation on bullet accuracy: 180 Scirocco produced best consistent groups but took twice as long to achieve. ABs produced accurate load with ease, but not as repeatable for unkown reasons.
