Winchester Ammo X2431 Super X243 Win 80 gr 3350 fps Jacketed Soft Point (JSP) 20 Bx/10 Cs

Winchester Super-X ammunition in .243 Winchester delivers the velocity and reliability that hunters and precision shooters depend on. The X2431 load pairs an 80-grain jacketed soft point (JSP) bullet with a 3,350 fps muzzle velocity, making it a balanced choice for medium-game hunting and target work where controlled expansion and penetration matter. Each box contains 20 rounds, sold in cases of 10 boxes for shooters who stock up for the season or practice extensively.

The .243 Winchester itself is one of the most versatile cartridges in North America—flat-shooting enough for longer-range work, mild enough for shooters sensitive to recoil, and effective on deer, antelope, and similar game when paired with the right bullet. The jacketed soft point design is engineered to expand reliably on impact while maintaining structural integrity for deep penetration, a trait that matters whether you're hunting or shooting steel at distance.

Winchester's Super-X line has earned its reputation through consistency and performance. This particular load balances velocity with controllable recoil and accuracy, making it a go-to option for hunters who want ammunition they can trust without guesswork or excess expense.

Frequently Asked Questions

What is .243 Winchester ammunition good for?

The .243 Winchester is a proven medium-game cartridge, accurate and effective on deer and antelope at hunting distances. It also works well for precision shooting and target practice due to its moderate recoil and flat trajectory. This 80-grain load is suitable for both roles.

What's the difference between jacketed soft point and hollow point?

A jacketed soft point has a soft lead tip exposed over a copper jacket; it expands on impact but tends to penetrate deeper than a hollow point. This design is preferred for hunting larger game where penetration is important. Hollow points expand more aggressively and are often used for smaller game or target work.

How much ammunition is in each case?

Each case contains 10 boxes of 20 rounds, for a total of 200 rounds per case.

Is Winchester Super-X accurate for long-range shooting?

Winchester Super-X is designed for accuracy and reliability, and the .243 Winchester cartridge itself is flat-shooting enough for extended-range work. Whether this load meets your specific precision requirements depends on your rifle, load expectations, and distance—we recommend testing it from your own firearm before committing to a larger purchase.
