That's kinda the predacessor to the Nosler Balistic Tip. Before polymer tips became the next trend for boosting a bullet's aerodynamic properties, they used bronze, aluminum, and copper.
OLD OLD Winchester "Silver tips" used a shiny/silvery material like Aluminum for their protective tips.
Anyhow, the bullet tip will upset the jacket/core upon impact and the bullet will generally act like other lead tipped spire points or expanding ammo. It's just that the pointy tip of the insert helps boost aerodynamic properties a bit so that it's closer to a match hollow point but doesn't have the limited expansion properties.
It's still possible to get the Remington 150grn bronze tips as reloading components I'm pretty sure, I think Midway stocks some of them. Not sure if they are still a Remington factory offering in loaded ammo though.
