Frequently Asked Questions

What is the best powder for a supersonic .300 Blackout hunting load with a 110gr Barnes TAC-TX bullet?

Based on testing by Johnny's Reloading Bench, Winchester 296 (H110) proved to be the superior powder for a supersonic .300 Blackout hunting load. It delivered exceptional consistency with low standard deviations and high velocities, outperforming Hodgdon Lil' Gun in this application.

What is the recommended OAL for a .300 Blackout hunting load using the 110gr Barnes TAC-TX bullet?

For the 110gr Barnes TAC-TX bullet in .300 Blackout, a recommended Overall Length (OAL) is 2.250 inches. This length ensures proper feeding in semi-automatic platforms and aligns with the bullet's crimping groove for consistent case tension.

Why are CCI #41 primers recommended for .300 Blackout AR-15 reloads?

CCI #41 primers are military-style small rifle primers that are designed to be less sensitive, reducing the risk of slam-fires when used in AR-15 platforms with floating firing pins. This enhances safety during reloading and shooting.

What were the key performance metrics for the chosen .300 Blackout hunting load?

The selected load featured 20.2 grains of Winchester 296 powder pushing a 110gr Barnes TAC-TX bullet. It achieved an impressive average velocity of 2451 fps with a low standard deviation of 4.7 fps and a tight group size of 0.56 inches.
