The Barnes TSX in .338 caliber, 185 grain is a solid-copper hunting bullet designed around one idea: punch deep and stay in one piece. Instead of a traditional lead core and jacket, the TSX is machined from 100 percent copper, so there's nothing to come apart on impact. On game it opens into four razor-sharp copper petals that cut through bone and heavy tissue while the bullet holds nearly all of its original weight. The boat tail profile cleans up the back end for a flatter, more stable flight, and this one carries a G1 ballistic coefficient of 0.352 with a sectional density of 0.231.
Those grooves cut into the shank aren't just for looks. They act as relief points as the bullet travels down the bore, which drops pressure, trims copper fouling, and helps the bullet shoot accurately at higher velocities. That's a real advantage with the TSX, since all-copper bullets run longer than their lead-core equals at the same weight and can be touchy about fouling in some barrels. The relief grooves take a lot of that headache off the table.
Barnes recommends starting around 0.050 inches off the lands, with most rifles finding their sweet spot somewhere between 0.030 and 0.070 inches depending on the barrel. It pays to spend a little range time working up the seating depth, because these bullets reward careful load development with excellent consistency. Introduced back in 2003, the Triple-Shock X earned its reputation as one of the most dependable hunting bullets Barnes has ever built, and the .338 185-grain is a favorite for everything from deer-sized game up through tougher, heavier animals.
For reloaders who want a lead-free bullet that penetrates like it means it, the TSX is about as proven as they come.
Yes. The TSX is machined from 100 percent copper with no lead core, so it stays together on impact and retains nearly all of its original weight. That all-copper construction is also what makes it a good fit if you hunt in areas where lead-free projectiles are preferred.
This is the standard TSX, which uses an all-copper hollow point nose rather than a polymer tip. The Tipped TSX (TTSX) adds a polymer tip for a slightly higher ballistic coefficient and faster expansion. Both penetrate deep and hold their weight, but if you want the plain hollow point design, the TSX is what you're looking at here.
Barnes suggests starting at about 0.050 inches off the lands as a baseline. Most rifles shoot their best somewhere between 0.030 and 0.070 inches off, so it's worth testing a few seating depths during load workup. Copper bullets like these tend to reward that extra bit of tuning with tighter groups.
The relief grooves cut into the shank are specifically designed to reduce copper fouling and lower pressure as the bullet moves down the bore. In practice that means less cleaning and more consistent accuracy at higher velocities. It's one of the reasons the TSX has stayed so popular with handloaders.
