The Barnes TSX in 8mm gives handloaders a proven all-copper hunting bullet in a .323 diameter, 200 grain, boat tail form. Since the Triple-Shock X arrived in 2003, it has earned a reputation as one of Barnes' most trusted big game projectiles, and this weight is a popular pick for anyone loading 8mm Mauser (the JS or S variant), 325 WSM, or 8mm Rem Mag. With a ballistic coefficient around .421 and a sectional density near .274, it carries energy well downrange while holding its line in the wind.
This is a solid copper bullet with no lead core and no jacket to separate, so it tends to hold nearly all of its weight after impact. On game, the hollow point nose peels back into four sharp copper petals, driving deep and pushing energy where it counts. The rings machined into the shank aren't just for looks. They give the copper somewhere to go as the bullet moves down the bore, which cuts fouling, eases pressure on hot loads, and often tightens groups.
Because copper is longer than lead for a given weight, seating depth and powder choice matter with these. Handloaders running 325 WSM have had good luck with powders like RL17 and H4350, and plenty report sub-MOA groups once they dial in the charge and jump to the lands. Barnes typically suggests starting a touch off the lands and working up. As always, cross-check current load data for your exact cartridge and rifle before you get rolling.
Hunters chasing deer, elk, moose, bear, and plains game who want reliable penetration and a clean exit tend to gravitate toward the TSX. It's also a smart choice for lead-free hunting areas without giving up terminal performance. Each box holds 50 bullets ready to load.
These .323 diameter, 200 grain bullets work in most 8mm rifles that take .323-inch projectiles, including 8mm Mauser (JS/S), 325 WSM, and 8mm Rem Mag. Handloaders often run them in the 325 WSM for big game. Just confirm your barrel is chambered for .323 bullets before loading, since some older 8mm Mausers use a smaller bore diameter.
These are unloaded reloading bullets, not finished cartridges. You'll need brass, primers, powder, and reloading equipment to assemble complete rounds. Each box contains 50 projectiles ready for your handloading bench.
The rings cut into the copper shank act as relief points as the bullet travels down the bore. This reduces pressure on higher-velocity loads, cuts down on copper fouling, and often improves accuracy. It's a big part of why the TSX shoots so consistently.
Because it's solid copper with no lead core to fragment, the TSX typically retains nearly all of its original weight. The nose opens into four copper petals for expansion while the base drives deep. That combination gives you reliable penetration on larger game.
