Marketing "ploy". I guess all marketing is a ploy to some degree. Silvertips were/are good bullets. They work. Now Zombiemax IS a marketing ploy. Black Talon, Silvertip, Gold Dot, Starfire, Golden Sabre, DRT. All marketing labels designed to set them apart from the rest of the competition.
In life, strive to take the high road....It offers a better field of fire.
