I think they are very competitive with the Hornady Interbond and Nosler Accubond. I've shot all these bullets with great success for accuracy. I've killed large deer with the Accubond and the terminal effects were tremendous. I assume the same results would be forthcoming from the Sciroccos and Interbonds due to their similarity in construction. The Barnes TSX is completely different construction; being monolithic and not of bonded construction. My experience with the 168gr. TSX in 30 cal. has been the best yet. Super accurate and better penetration than any other 180gr. 30 cal bullet I have fired through my 300 WM.
