When shooting a Vegas-style target, a perfect score is 300 with 30X. The perfect arrow to achieve such an accomplishment is a Gold Tip 30X. With an outside diameter of 26/64, the 30X is the largest diameter carbon arrow made. The 30X gives you all the perfection of a Gold Tip with the extra large diameter needed to give you the X-cutting advantage what will put you over the top. The 30X Pro has a straightness tolerance of +/-.001" and a weight tolerance of one grain per dozen.
