Description
Fort Scott Munitions brings their proven Tumble Upon Impact technology to the .243 Winchester platform with this 70-grain solid copper load. Every bullet is machined from premium copper on precision CNC lathes, giving you the tight tolerances that matter when accuracy counts. The monolithic construction means no jacket, no hollow cavity, and no fragmentation to deal with.
How TUI Technology Works in the 243 Win Load
When these bullets strike soft tissue, they travel straight through initial barriers before beginning to tumble end-over-end. This creates a larger wound cavity than the bullet's diameter while maintaining impressive penetration. The damage occurs primarily inside rather than at first contact, which makes these rounds effective for medium game hunting without the unpredictable performance issues you get with traditional hollow points. Fort Scott's projectiles retain over 95 percent of their mass on impact, so you get consistent results shot after shot.
Performance and Practical Use
Loaded to 3590 fps with 2003 ft-lbs of muzzle energy, this 70-grain load sits in a sweet spot for varmint hunting and precision rifle work. The .243 Winchester itself is renowned for flat trajectory and minimal recoil, making it one of the most shootable rifle cartridges available. These solid copper rounds add the benefit of being usable where lead ammunition is restricted, expanding where you can actually hunt. Whether you're running them through a bolt action or a modern precision rifle, the consistency Fort Scott delivers means you can trust your point of impact from the first round through your entire magazine.
What You're Getting
Each box contains 20 rounds of match-grade ammunition loaded in reloadable brass cases. If you reload, these cases are an asset rather than a disposable component, which adds real value over time. The ammunition ships ready to go, so there's no special prep work needed before heading to the range or field.

Frequently Asked Questions
How does the TUI technology in this .243 ammunition work differently from regular hunting rounds?
The Tumble Upon Impact design allows the solid copper bullet to penetrate straight through initial barriers before rotating end-over-end inside soft tissue. This creates a larger wound channel than the bullet diameter while maintaining deep penetration. The key difference is that damage occurs primarily internally rather than at first contact, and there's no expansion failure like you can get with traditional hollow points.
Can I use Fort Scott Munitions .243 Win TUI in areas where lead ammunition is prohibited?
Yes. These are fully lead-free solid copper projectiles, so they're suitable for use in areas with lead restrictions. That said, if you've been shooting lead ammunition in your barrel, Fort Scott recommends cleaning your barrel thoroughly before switching to solid copper to maintain accuracy.
Are the brass cases reloadable?
Yes, the ammunition ships in reloadable brass cases. If you already reload, these cases have real value and aren't just disposable components. Each box contains 20 rounds loaded to match-grade standards.
What's the effective range for hunting with these .243 Winchester 70 gr loads?
The .243 Winchester is known for flat trajectory and accuracy to 300 yards and beyond. At the 3590 fps velocity Fort Scott delivers with this load, you have solid performance out to practical hunting ranges. For medium game like deer-sized animals, shot placement is more important than raw distance, and the low recoil of the .243 makes that surgical accuracy easy to achieve.
