The July 2004 issue of Petersen's Hunting had an article written by Rick Jamison with photos comparing the different 180 grain, 30 cal bonded bullets having 2000 and 3000 fps impacts into ballistic gelatin. All the bullets seemed to perform well. With the high impact velocity, the Nosler AB penetrated 15.5" and retained 61% weight. The Scirocco penetrated 16.0" and retained 79% weight. IMO, the bullet that had the best combination of penetration, retained weight, and expansion diameter, was the Trophy Bonded BearClaw (but its B.C. is low in comparison).
The Nosler Accubond can be thought of performing like a partition with a polymer tip. In my 300 WSM, I have found the 180 & 200 grain Accubonds to be more accurate than the 180 & 150 gr Sciroccos, in fact more accurate than any other bullet I've tried in that rifle. I used a 200 grain accubond on a bull elk last year. It retained 135 out of 200 gr(68%) and was recovered just under the hide of the offside shoulder. The only bone hit was a rib. Went through both shoulder muscles, but no blades.
I think the Sciroccos and the Accubonds would be great for deer-not too much. I have had real good performance with the 180 Sciroccos on 4 deer and 5 feral pigs (no recovered bullets to examine). I will be using the 180 Accubond for my two deer hunts this fall.
