Winchester Copper Impact Ammunition 300 Winchester Short Magnum (WSM) 150 Grain Copper Extreme Point Polymer Tip Lead-Free 20RD

Winchester Copper Impact ammunition in 300 WSM delivers a modern, non-toxic hunting round engineered for consistent performance in a versatile magnum platform. Built on Winchester's extensive ammunition heritage, these 150-grain copper loads combine reliable ballistics with lead-free construction—ideal for hunters in jurisdictions requiring non-toxic ammunition or those simply choosing lead-free options without compromise. The 20-round pack gives you enough to work up a load, practice, and hunt with confidence.

The heart of Copper Impact is its solid-copper Extreme Point bullet, designed to maximize terminal performance at typical hunting distances. The oversized impact diameter creates more shock on impact and energy transfer into the target, translating to faster, more decisive knockdown. The red, reinforced polymer tip aids ballistic efficiency while supporting the bullet's expansion characteristics. Because it's solid copper rather than a traditional lead core, you get superior weight retention through the target, meaning deeper penetration and more consistent energy dump downrange—critical for medium to large game taken at moderate to long range.

Ballistic design matters too. The streamlined profile and boattail configuration keep these rounds supersonic longer and flatten your trajectory, reducing holdover adjustments between typical hunting yardages. The hollow nose cavity and solid construction work together to ensure lethal terminal performance without relying on lead, making these rounds a clean choice for hunters who demand both ethics and effectiveness.

Frequently Asked Questions

Is Winchester Copper Impact ammo suitable for hunting medium to large game?

Yes. The solid-copper Extreme Point bullet and oversized impact diameter are designed to deliver energy transfer and penetration appropriate for hunting applications. Typical hunting distances in the 300 WSM range are well within the ballistic envelope of this load.

Why choose lead-free ammunition?

Lead-free rounds comply with non-toxic ammunition regulations in many states and hunting zones. They're also a choice for hunters who prefer to eliminate lead from the field and their supply chain. Winchester Copper Impact rounds deliver lead-free performance without sacrificing terminal effectiveness.

What is the ballistic advantage of the boattail and streamlined profile?

The boattail and streamlined design reduce drag, helping the bullet maintain velocity and energy downrange, which flattens your trajectory and extends the effective range of the load. This means fewer hold-over adjustments across typical hunting distances.

How many rounds are in a box of Winchester Copper Impact 300 WSM?

Each box contains 20 rounds.
