Our reloading data for the .260 | 87gr | Speer HP TNT bullet covers a total of 13 suitable calibers and 662 load recipes

The Speer TNT bullet is designed with a thin, gilded metal jacket and an explosive hollow point specifically engineered for rapid expansion upon impact. This construction ensures superior performance for varmint and small game hunting applications, where instant energy release and maximum tissue disruption are essential. The bullet typically exhibits frangible characteristics, leading to an expansion that results in extensive energy dispersion with minimal penetration. Weight retention is generally low due to the intentional fragmentation, making it unsuitable for large game or scenarios requiring deep penetration and high retention. Suitable for calibers commonly used in varmint hunting, such as .223 Remington and .22-250 Remington, the Speer TNT is favored among handloaders for its predictable performance and ease of loading. Its lightweight construction and consistent expansion characteristics serve the handloader by allowing customization in seating depth and velocities to maximize accuracy and terminal effect on smaller targets.

About this bullet

.260 | 87gr | Speer HP TNT is a bullet made by Speer. At 87 gr (5.6 g) and a diameter of 0.26'' (6.60 mm) it suits handloads where bullet weight and barrel length have to be matched carefully. Its G1 ballistic coefficient of 0.337 drives velocity retention and wind drift downrange — higher values mean a flatter trajectory at distance. A twist rate of 1:9.5 is recommended for stable flight; slower twists can under-stabilise this bullet. We currently list 662 load recipes across 13 calibers for this bullet.
