Winchester Ballistic Silvertip Ammunition 300 Winchester Short Magnum (WSM) 180 Grain Rapid Controlled Expansion Polymer Tip 20RD

Winchester Ballistic Silvertip ammunition in 300 Winchester Short Magnum (WSM) delivers the kind of terminal performance that serious hunters expect from a rifle load engineered for medium to large game. The 180-grain polymer-tipped bullet combines a streamlined design for ballistic efficiency with Winchester's controlled expansion technology—engineered to open reliably on impact while maintaining structural integrity for deep, consistent penetration. Built for hunters who demand accuracy and stopping power in a magnum-length action, this is the round to reach for when hunting at distance in open country or when taking shots where precision and energy retention matter.

The 300 WSM has earned its reputation as a flat-shooting, fast-killing alternative to the full-length 300 Win Mag, with less recoil and a shorter action that fits well in modern hunting rifles. At a muzzle velocity of 3010 fps and muzzle energy of 3621 foot-pounds, this load demonstrates the kind of velocity and retained energy that makes the WSM a favorite for western hunting and long-range work. Winchester's Ballistic Silvertip line is built on decades of ammunition engineering, and this load reflects that heritage—consistent performance you can trust when it counts.

Sold in boxes of 20 rounds, this is ammunition for hunters who reload or purchase in bulk and want consistency across their supply. Whether you're sighting in for elk season or running a proven load through a rifle that's already proven itself on game, Winchester Ballistic Silvertip in 300 WSM is a straightforward choice backed by field results.

Frequently Asked Questions

What rifles will this ammunition work in?

Winchester Ballistic Silvertip 300 WSM is designed for rifles chambered in 300 Winchester Short Magnum. Check your rifle's chamber marking or consult your owner's manual to confirm it is chambered in 300 WSM before firing.

Is this ammunition suitable for long-range hunting?

Yes. The 180-grain polymer-tip bullet at 3010 fps muzzle velocity and 3621 foot-pounds of energy is designed for hunting applications at distance. The polymer tip supports a streamlined ballistic profile that retains velocity downrange, making it a solid choice for medium to long-range hunting scenarios typical of the 300 WSM platform.

How much ammunition is in a box?

Each box contains 20 rounds. Cases of this ammunition contain 200 rounds (ten boxes).

What is "controlled expansion" and why does it matter?

Controlled expansion refers to the bullet's design to open reliably upon impact while maintaining structural integrity for consistent penetration. This engineering helps ensure that the bullet delivers energy to vital areas rather than fragmenting unpredictably, which is important for ethical, effective hunting.
