DTAC Load Data
Our DTAC load data covers 5,291 load recipes for 1 bullets and 18 calibers. Find all bullets and reloading data below and compare the performance of different powders for each bullet and caliber combination side-by-side.
David Tubb’s DTAC bullets, particularly the 6mm 115-grain variants, are engineered for precision long-range shooting. These bullets feature a Rebated Boat Tail (RBT) design, which enhances the bullet’s ability to seal the bore upon firing, reducing gas blow-by and potentially extending barrel life . The RBT design also contributes to consistent ballistic performance, with a reported G1 Ballistic Coefficient (BC) of 0.620, indicating excellent aerodynamic efficiency.
To further improve performance, Tubb introduced the NOSERING modification—a precision-cut ring near the bullet’s tip. This feature promotes controlled expansion upon impact, making the bullet suitable for both target shooting and hunting applications. Additionally, the NOSERING enhances shot-to-shot drag uniformity, resulting in tighter vertical groupings and more consistent BC values.
For barrel maintenance, Tubb offers the FinalFinish and Throat Maintenance System (TMS) bullet kits. These kits use abrasive-coated bullets to smooth out imperfections in the barrel, reducing fouling and making cleaning easier. Regular use of TMS rounds can help maintain throat integrity and prolong the barrel’s accurate life .

About DTAC load data on XXL Reloading
This page collects every DTAC bullet we hold reloading data for, grouped by caliber and bullet weight. Each caliber and bullet combination links to a detail page with powder-by-powder load recipes: powder brand and type, start and maximum charge weight in grains and grams, case fill ratio, calculated peak chamber pressure, muzzle velocity and the barrel length the load was computed for.
Unlike a manufacturer's own tables, our DTAC data is generated with an inner-ballistics engine across the full powder range, so you can compare many powders side by side for the same bullet instead of the handful a single load manual prints. Charge weights, pressures and velocities are modelled consistently, which makes cross-powder and cross-caliber comparison meaningful when you work up a load.
Use the caliber and bullet-weight filters above to narrow the list, switch to the Bullets tab to browse the DTAC product range, and open any combination to see the full load table. All data is calculated reference data for experienced handloaders: always start at the minimum charge, work up carefully in your own rifle, and cross-check against current published data before firing.
