Description
The Barnes TSX in .224 diameter is one of those projectiles that earned its reputation the hard way, by performing in the field year after year. These 53-grain flat base bullets are machined from 100 percent copper with no lead core, so instead of coming apart on impact they roll back into four sharp cutting petals and drive deep while holding onto almost all of their original weight. For reloaders working up loads for .223 Remington, .22-250, and other .22 centerfires, that consistency is exactly what makes the TSX worth the bench time.
What Sets the Barnes TSX Flat Base Apart
The signature feature here is the series of precisely cut grooves, or relief rings, machined into the bullet shank. As the copper flows under pressure traveling down the bore, it expands into those grooves rather than pushing forward. The practical result is lower pressure, noticeably less copper fouling, and the ability to safely push these to higher velocities than a solid copper bullet would otherwise allow. Those rings also help settle barrel harmonics, which is a big part of why so many reloaders find the TSX shoots tight once they dial in a load.
Loading the .224 53gr TSX
This bullet carries a sectional density of 0.151 and a G1 ballistic coefficient of 0.204, with an overall length right around 0.796 inches. Because the all-copper design runs longer than a comparable lead-core bullet of the same weight, Barnes recommends a 1:12 inch twist or faster to keep it stabilized. A touch more case capacity gets eaten up by that extra length, so seating depth and a proper crimp in the cannelure are worth paying attention to when you're building loads. Barnes publishes solid load data for this exact bullet, which takes a lot of the guesswork out of starting pressures.
For varmint hunters, predator callers, and anyone who wants a lead-free option that still punches above its weight class, the .224 53-grain TSX delivers the kind of repeatable terminal performance that keeps handloaders coming back to it.

Frequently Asked Questions
Are these Barnes TSX .224 bullets loaded ammunition?
No. These are component bullets for handloading only, sold 50 to a box. You'll need to supply your own brass, primers, and powder to assemble finished cartridges.
What barrel twist do I need for the 53gr TSX in .224?
Barnes recommends a 1:12 inch twist or faster to stabilize this bullet. Because the all-copper construction makes it longer than a lead-core bullet of the same weight, twist rate matters more than you might expect. Most modern .223 and .22-250 barrels will handle it just fine.
Why does the Barnes TSX have those rings cut into the body?
Those are relief grooves that let the copper flow outward instead of forward as the bullet travels down the bore. They cut pressure, reduce copper fouling, and let you load to higher velocities, and they tend to help accuracy by smoothing out barrel harmonics.
What cartridges can I load these .224 53gr bullets in?
They work in the full range of .22 centerfires that use a .224 projectile, including .223 Remington and .22-250 Remington. Barnes publishes load data for this exact bullet across those cartridges, so check their current data for starting charges and overall length.
