Barnes TSX Bullets 9.3mm .366" 250 gr FB 50/ct

The Barnes TSX 9.3mm rifle bullet is purpose-built for hunters pursuing large game where reliable expansion and deep penetration matter. These .366" 250-grain monolithic copper projectiles deliver the controlled, violent expansion you need to anchor game cleanly in the field. Whether you're handloading for a 9.3x62 or similar cartridge, the TSX represents a proven design trusted by serious hunters who demand bullets that perform consistently from shot to shot.

What sets the TSX apart is its construction: pure copper, no jacket-to-core separation, and engineered to create four sharp-edged petals on impact while retaining 100 percent of its original weight. This combination means the bullet won't fragment in bone or soft tissue, and it won't shed weight as it passes through. For elk, moose, red stag, and other tough game, that durability translates to deeper, more predictable wound channels and better odds of a one-shot kill.

Handloaders appreciate the TSX's consistent performance and straightforward seating. Optimal accuracy typically emerges when you seat these bullets 0.03 to 0.07 inches off the lands—a range you can fine-tune for your specific rifle. Each box contains 50 bullets, giving you a solid quantity for load development and hunting season prep without the commitment of a thousand-round brick.

Frequently Asked Questions

What rifles and cartridges is the 9.3mm .366" TSX compatible with?

These bullets are designed for 9.3mm rifle cartridges, including the 9.3x62, 9.3x65, and similar European and African hunting rounds. Verify that your rifle's bore diameter matches .366" and that your reloading data specifically references the TSX bullet before handloading.

How do I seat these bullets for best accuracy?

Barnes recommends seating the TSX 0.03 to 0.07 inches from the lands, depending on your individual rifle. Start at the longer distance and work shorter while chronographing and grouping on paper. Your rifle will tell you where it shoots best; don't force a load that doesn't group well.

Will the TSX bullet lose weight during expansion and penetration?

No. The monolithic copper design is engineered to retain 100 percent of the original bullet weight during expansion and penetration. This means no core separation, jacket fragmentation, or weight loss—just a larger, sharper wound cavity and consistent deep penetration.

Is 250 grains the right weight for my big game hunt?

The 250-grain TSX is a common load for 9.3mm cartridges and suits large game such as elk, moose, and red stag. Verify that your rifle's reloading manual includes data for the 250-grain TSX at your intended velocity, and consult your hunting guide or mentor if you're uncertain about bullet choice for your specific game and distance.
