The 95 grain Nosler Ballistic Tip would be my choice if limited to a 10" twist. Although some of the other bullets in the 95 and 100 grain weight range advertise a higher ballistic coefficient, my field experience suggests Nosler's advertised B.C. figures are pretty conservative. This bullet is good out to about 600 yards - beyond that, you really need the heavier VLD bullets. Roscoe
