So the silvertips fragment or mushroom like cd ammo? I just never shot anything silver tipped and had no idea the purpose.Winchester Silvertips was the Ammo everyone had to have before the Black Talons came along. In the early eighties we were issued .357 Silvertips as duty ammo. When I went through the transition course and started carrying a semi-auto I was issued .45 Silvertips. I think I still have a few rounds of each buried on the shelf in the gun cave.
