My experience with the .30 caliber Scirocco's in the .300 Win Mag has been very good. The 180 gr. is about ideal for elk. Swift says the 165 grain is about at its upper limit on elk out of this caliber. The 150 grain Scirocco's were a little soft for elk even out of a .308 Winchester - Swift recommends them for deer sized game. Have killed a number of elk with the 130 grain .270 . Been right there when several were killed with the 150 grain 7MM out of a 7 Rem Mag. These bullets consistently put these big animals down hard. They expand to a big frontal diameter after they get through the ribs, making a very large wound channel through the lungs, and retain a good percentage of their of weight.

On the down side, the pure copper jacket fouls the barrel a little more than the accubond and builds a little more pressure at the same charge. It also seems that the accubonds break big bones a better - smaller frontal area - and penetrate maybe 25% more. But the Scirocco's, if your gun will shoot them, really put animals on the ground in a hurry - particularly with a broadside rib shot. I like 'em.
