Hi guys. A friend gave me a bunch of ammo a while back (had to get rid of it for legal reasons -- domestic troubles if ya know what I mean). Some are reloads, much is new. One box looks "new" (though very old). It is a green and yellow Remington box and is labeled something like 150 grain, bronze-tipped .30-06. What's the deal with these? What are bronze-tipped rounds best used for? I like the looks, just curious as to what they are designed for.

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.

EXPRESS® BRONZE POINT™ TIPPED BULLET
A superb choice for long-range medium game. The high ballistic coefficient of the bronze insert produces a flat trajectory and maintains high velocity and energy at extreme ranges. Yet on impact, the tip is driven backward to create rapid expansion that is controlled to optimum limits by the pre-grooved jacket, even on thin-skinned game. The tip also protects the bullet nose from being deformed by recoil while in the magazine.

Thanks guys! I appreciate the info. Will save the box for the event that I need some decent medium-size big game ammo.
