Description
The Barnes TSX in .25 caliber is a 100 grain, all-copper hunting bullet built for the handloader who wants reliable terminal performance without the lead core. At .257 diameter with a 1.116" overall length, it drops right into popular cartridges like the .25-06 Remington, .257 Roberts, and .257 Weatherby Magnum. On impact the nose peels back into four cutting petals while the shank holds together, which is why these bullets routinely retain close to 100 percent of their original weight and drive deep through bone and muscle. The boat tail base helps the bullet hold velocity downrange, and with a G1 ballistic coefficient of .336 and sectional density of .216, it carries enough energy for open-country shots on deer, antelope, and similar medium game.
What Makes the Barnes TSX Tick
The TSX earned its reputation on the pressure-relief grooves machined into the shank. Those rings give the displaced copper somewhere to go as the bullet engraves the rifling, which keeps pressures reasonable, trims copper fouling, and helps a lot of rifles shoot tighter groups. Barnes introduced the TSX back in 2003 and it quickly became their most popular hunting bullet, and that staying power says a lot about how it performs in the field.
Loading the .25 Caliber TSX
Monolithic copper bullets like to be treated a little differently than cup-and-core. A clean bore before your first shots goes a long way, and most reloaders find these shoot best with some jump to the lands. Barnes suggests starting around .050" off the rifling as a minimum, and plenty of folks have had groups come together even farther back than that. Work up your load carefully with current data for your cartridge and you'll typically find a sweet spot that prints well under an inch at 100 yards.
For the hunter chasing mule deer, whitetail, pronghorn, or sheep with a .25 caliber rifle, this 100 grain TSX is a proven, lead-free option that punches above its weight and holds together when it matters.

Frequently Asked Questions
What cartridges do these Barnes TSX .25 caliber bullets work in?
These .257 diameter, 100 grain bullets are a component for reloading any .25 caliber rifle cartridge, including the .25-06 Remington, .257 Roberts, and .257 Weatherby Magnum. They're a popular choice for 100 grain loads in those cartridges. Always build your loads using current published data for your specific cartridge.
Why does the Barnes TSX foul less than regular bullets?
The TSX has multiple pressure-relief grooves cut into the copper shank that act like relief valves as the bullet travels down the bore. That design reduces the amount of copper being scraped into the rifling, which means less fouling buildup and often better accuracy. Starting with a clean bore before shooting copper bullets helps even more.
How much bullet jump should I use when loading the .25 caliber TSX?
Monolithic copper bullets like the TSX generally shoot best with some jump to the lands. Barnes recommends starting around .050" off the rifling as a minimum, and many reloaders find their best groups farther back than that. It's worth testing a few seating depths to find what your particular rifle prefers.
Is the Barnes TSX a good hunting bullet for deer and antelope?
Yes, the all-copper TSX is built specifically for hunting and is known for deep, straight-line penetration with nearly full weight retention. On impact the nose opens into four cutting petals for reliable expansion, making the 100 grain .25 caliber version a solid pick for deer, antelope, and similar medium game. It's one of Barnes' most trusted hunting bullets for exactly this reason.
