300 BLK Supersonic Hunting Load with 120gr Barnes TAC-TX

Published on February 14, 2017
Duration: 32:21

This video details the process of developing a supersonic hunting load for the 300 Blackout cartridge, specifically using 120gr Barnes TAC-TX bullets. The instructor, Johnny, focuses on efficiency due to an upcoming hog hunt, selecting H110 powder and CCI #450 primers. He demonstrates the loading process, including optional case flaring, and then proceeds to range testing to determine an optimal charge weight. The video also covers zeroing a rifle equipped with a red dot sight and iron sights for hunting applications.

Quick Summary

For 300 Blackout supersonic hunting loads, H110 powder is recommended with 120gr Barnes TAC-TX bullets. A charge of 17.5 grains of H110 achieved approximately 2200 ft/s with a 1.41-inch group at 100 yards. A 75-yard zero is ideal for hog hunting, providing point-and-shoot capability out to 150 yards.

Frequently Asked Questions

What powder is recommended for 300 Blackout supersonic hunting loads?

For supersonic 300 Blackout hunting loads, H110 powder, also known as Winchester 296, is highly recommended due to its consistent performance and suitability for this cartridge. It's a popular choice for achieving good velocities and accuracy.

What are the optimal charge weights for 120gr Barnes TAC-TX bullets in 300 Blackout?

Barnes' published data suggests a starting charge of 16.5 grains and a maximum of 17.5 grains of H110 for the 120gr TAC-TX. Testing showed that 17.5 grains achieved approximately 2200 ft/s with good accuracy, making it a viable hunting load.

How do you sight in a 300 Blackout rifle for hog hunting?

For hog hunting with a 300 Blackout, a 75-yard zero is recommended. This setup allows for point-and-shoot accuracy out to approximately 150 yards, which is ideal for typical hunting distances. It's advisable to use cheaper ammunition for initial sight-in before confirming with hunting rounds.

What is the effective range of a 300 Blackout with a 120gr Barnes TAC-TX load?

With a 120gr Barnes TAC-TX bullet loaded to supersonic velocities around 2200 ft/s and a 75-yard zero, the 300 Blackout is effective for hog hunting out to about 150 yards. Beyond this range, bullet drop becomes more significant.
