Published on June 23, 2017
Duration: 32:06

This video details the process of reloading 300 Blackout ammunition using 115gr Lehigh Defense Controlled Chaos bullets. The instructor tests two powders, Alliant Power Pro 300 MP and Winchester 296, across different charge weights in both an 8.5-inch SBR and a 16-inch rifle. Comprehensive ballistics data, including velocity, standard deviation, and group sizes, is presented for each load, offering insights into optimal supersonic performance.

Quick Summary

Reloading 300 Blackout with 115gr Lehigh Defense Controlled Chaos bullets involves using powders like Alliant Power Pro 300 MP or Winchester 296, seated to an overall length of 2.110 inches. Testing in a 16-inch rifle yielded sub-inch groups, while an 8.5-inch SBR showed more variability. Winchester 296 generally provided superior velocity consistency and standard deviation.

Frequently Asked Questions

What are the key characteristics of the 115gr Lehigh Defense Controlled Chaos bullet for 300 Blackout?

The 115gr Lehigh Defense Controlled Chaos bullet is an all-copper projectile designed for controlled expansion. It features a unique grooved design and a front section that fragments into multiple pedals upon impact, while the base ensures deep penetration, making it effective for hunting and self-defense applications.

Which powders are recommended for reloading 300 Blackout with 115gr Lehigh Defense Controlled Chaos bullets?

The video tests Alliant Power Pro 300 MP and Winchester 296 (Hodgdon H110). Both are considered effective supersonic powders for 300 Blackout. Winchester 296 generally offers slightly better velocity consistency and standard deviation, while Power Pro 300 MP is a close performer, especially in longer barrels.

What is the recommended overall length for 300 Blackout reloads using 115gr Lehigh Defense Controlled Chaos bullets?

The recommended overall length for 300 Blackout cartridges loaded with the 115gr Lehigh Defense Controlled Chaos bullet is 2.110 inches. This length ensures proper feeding and function in most 300 Blackout firearms.

How does the 8.5-inch SBR compare to a 16-inch rifle when shooting 300 Blackout with these reloads?

The 16-inch rifle demonstrated significantly better accuracy and more consistent performance with the tested loads compared to the 8.5-inch SBR. The shorter barrel of the SBR showed more variability in accuracy, suggesting it is more sensitive to load variations.
