Keith,
If the Scirocco's group that well shoot it. This bullet is designed specifically for the ultra high velocity of the RUM line and Weatherby's. I've only killed 2 deer and an antelope with mine and the animals were quite dead quite fast but that's not many animals. The gun grouped well with my handloads. Remington doesn't load the scirocco in the 7mm RUM for some odd reason yet but does for the 300.
