There are five bullets in the A-Tip line: the 110-grain 6mm, a 135-grain 6.5mm, a 153-grain 6.5mm, a 230-grain .308, and a 250-grain .308. Like many of the hottest match bullets today, the A-Tips are heavy. Part of that weight comes from the tip itself. Compared to a hollow-point or a plastic insert, the A-Tip puts more weight up front, and because the aluminum tip is longer than a polymer insert, it also lengthens the bullet’s ogive. Because they are heavy, they will do best in barrels with faster twist rates.
