The Barnes Bullets TSX BT .510 647gr bullet is a premium all-copper projectile engineered for reloaders pursuing large game at distance. This 20-pack of TSX (Triple-Shock X) bullets delivers the terminal performance serious hunters demand—controlled expansion, deep penetration, and weight retention through heavy bone and muscle. Built entirely from copper, these projectiles are free of lead and designed to expand reliably across a wide range of velocities, making them versatile for handloads dialed in to your specific rifle.
The TSX BT's design produces four razor-sharp petal expansion upon impact, generating a wide wound channel while maintaining structural integrity through dense tissue. For reloaders working up loads in ultra-large calibers, the combination of mass (647 grains) and construction means you're not just throwing lead downrange—you're building a cartridge capable of ethical one-shot kills on big game. Whether you're developing loads for a .510 DTC, .500 Nitro, or similar heavy rifle, these bullets reward careful handloading with consistent accuracy and terminal performance.
Seating depth matters with TSX bullets. Barnes recommends a seating range of 0.03 to 0.07 inches off the lands, adjusted to your rifle's chamber and intended velocity. This window allows you to optimize for both accuracy and expansion characteristics specific to your handload. Each 20-pack provides enough material to work up several accurate loads and field-test your cartridge before committing to a hunting trip.

Frequently Asked Questions
What caliber rifles do .510 647gr TSX bullets work with?
These are .510-diameter bullets sized for ultra-large caliber rifles chambered in .510 cartridges such as .510 DTC Europ, .500 Nitro Express, and similar big-bore magnums. Confirm your rifle's bullet diameter before purchasing.
What makes the TSX BT different from other all-copper bullets?
Barnes TSX (Triple-Shock X) design expands into four razor-sharp petals while retaining 100% of the original bullet weight. The BT profile is optimized for aerodynamic consistency. This combination produces deep, wide wound channels ideal for large game at extended range.
How should I seat these bullets in my reloads?
Barnes recommends seating TSX bullets 0.03 to 0.07 inches from the lands of your specific rifle's chamber. Work up your load within this range, testing for accuracy and feeding to find the optimal seating depth for your rifle and handload.
Are these bullets suitable for reloading from scratch?
Yes. These are component bullets sold for handloading. You'll need reloading equipment, brass cases, primers, and powder to assemble finished cartridges. Each 20-pack provides sufficient bullets for working up and testing loads before a hunt.
