'Silvertip' was Winchester-Western's marketing term for factory hunting rifle ammo that was loaded with bullets designed for deeper penetration than their 'Power Point" bullets. The term is also used to denote a line of their handgun ammo whose bullets are silver in color.
In the past, W-W often coated the lead bullets in their HG ammunition with a copper wash, I believe it is called, to make their ammo more attractive to the eye. Remington did not.
