Winchester® ammunition has been at the forefront of innovation for almost 140 Years,and today, Winchester® has succeeded in pushing limits even further back with its exclusive new bullet: the POWER MAX Bonded®.
Its exceptional performance is the fusion of a unique combination of 3 technologies which work together in the form of an integrated system:

• Lead core bonded to the copper alloy jacket
• Protected hollow point
• Contoured variable thickness jacket


In Power Max Bonded™, thanks to the bonding process, the core and the jacket expand together without breaking or separating. The bullet has a very high weight retention which means maximum energy for lightening knockdown power and very deep penetration. The absence of any fragmentation of the bullet, despite its wide diameter after expansion (twice the initial diameter) guarantees an important permanent cavity, without any damage to flesh.

The protected hollow point guarantees fast optimal expansion at all distances and impact speeds. Moreover, with this design, the end of the bullet is kept in perfect condition when you load or unload your rifle, which is a decisive element for guaranteeing extreme accuracy.

Last but not least, jacket thickness at every point of the bullet has been studied to provide optimal expansion: a thinner tapered part at the front for providing perfect expansion at all impact speeds and for all types of game, thicker towards the back of the bullet for controlling the expansion process and guaranteeing high weight retention. In this way, the jacket's design adds even more to the bonding technology.
