300 BLK Pistol/SBR Supersonic Hunting Load with 110gr Barnes TAC-TX - followup
This video details a follow-up load development for 300 Blackout supersonic hunting rounds using 110gr Barnes TAC-TX bullets in an 8.5-inch SBR. The instructor incrementally increased the Winchester 296 powder charge from 20.2 grains up to 21.0 grains, observing group sizes and chronograph data. The goal was to achieve higher velocities and tighter groups than previously obtained, while monitoring for pressure signs. The experiment concluded that the optimal load for this platform likely lies between 20.2 and 20.4 grains of W296, yielding approximately 2200-2250 fps with acceptable accuracy for hunting within 100 yards.
