The Remington Bronze point had a tip of I guess bronze in the same manner as the current tipped cartridges like Noslers Ballistic tips and other current tipped bullets.
The Silver tip was just a thin cap over a normal lead point in place and said to protect the point. It always worked for me and killed deer just fine. Never used the Remington bullet (Bronze Point) but IIRC it was Jack O'Connor who said they either penciled though or blew up like a bomb. Never used them that I can recall so can't say if Jack was right.

Our forefathers did not politely protest the British.They did not vote them out of office, nor did they impeach the king,march on the capitol or ask permission for their rights. ----------------They just shot them.
