The Barnes TSX 7mm (.284) 120gr Boat Tail is a component bullet for handloaders who want dependable terminal performance without the mess of lead-core fragmentation. Machined from 100% copper, the TSX carries no lead and holds together on impact, which is exactly what you want when the shot angle isn't perfect and you need the bullet to drive through bone and tissue. On expansion, the nose peels back into four razor-sharp petals that roughly double the original diameter, opening a wide wound channel while the shank keeps pushing forward.
The secret to the TSX is the set of relief grooves cut into the shank. Those grooves reduce bearing surface and give the copper somewhere to displace as it engages the rifling, which cuts down on pressure and, more importantly to most reloaders, keeps copper fouling to a minimum. That was the knock on the original Barnes X bullets years back, and the grooved TSX design put it to rest. This 120-grain projectile measures .284 in diameter, runs 1.125 inches long, and carries a G1 ballistic coefficient of 0.349 with a sectional density of 0.213.
Copper bullets like their own seating depth, and Barnes gives you a solid starting point: seat about 0.050 inch off the lands, then experiment anywhere from 0.030 to 0.070 inch to find the sweet spot for your particular rifle. A little load development goes a long way here. Guys running these in the 7mm-08, 7mm Rem Mag, 280 Rem and similar rounds have had great results on deer, antelope and hogs, and driven fast, the light 120-grain pill hits hard and shoots flat.
Bottom line, this is a lead-free hunting bullet with a proven track record and a reputation for consistency. If you handload and want a projectile you can trust to hold weight and penetrate straight, the 7mm 120gr TSX earns its spot on the bench.
These are component bullets for handloading, not loaded ammunition. You'll need brass, primers, powder and dies to assemble finished cartridges. They're a popular choice for reloaders working up hunting loads in 7mm cartridges.
Barnes suggests starting around 0.050 inch off the lands, then testing between 0.030 and 0.070 inch to dial in accuracy. Copper bullets can be a bit picky about seating depth, so a little load development pays off. Every barrel is different, so let your groups tell you where it likes to sit.
The TSX has relief grooves cut into the shank that reduce bearing surface and help minimize copper fouling. This was the fix for the fouling complaints tied to the older Barnes X design. Most shooters report fouling on par with traditional lead-core bullets.
This all-copper bullet is a solid pick for deer, antelope and hogs, and it holds together well thanks to near-total weight retention. Driven at good velocity in cartridges like the 7mm-08 or 7mm Rem Mag, the light 120-grain bullet shoots flat and penetrates deep. It expands reliably while pushing straight through.
