RE: Rem. Premier Scirocco Bonded ammuniton??
My experience so far with the Scirocco is that it expands slower and stays together better than the Ballistic Tip. The 130 grain .270, the 150 grain 7MM, and the 165 and 180 grain .30 calibers; have proven to be very good all around elk bullets. The 150 grain .30 caliber is too soft for elk - appears to be designed for deer size game. I tried the 90 grain 6MM on elk last fall, and it also appears to be in a little over its head on an animal this big.
The Ballistic Tips are great varmint bullets; and superb deer and antelope bullets in the heavier weights. I think Nosler recommends them for game up to Caribou size - and then for rib shots only.
Accuracy with both bullets has been very good - sub MOA in most of my guns.
