Testing the cheapest 308 Winchester Ammo in my M14

Published on November 15, 2025
Duration: 9:15

This video details the process of testing affordable, handloaded .308 Winchester ammunition in semi-automatic rifles like the M14 and M1A. The host, Deuce, uses a chronograph to measure muzzle velocity (2642 FPS with a lower charge) and assesses accuracy, aiming for 'fun' rather than sub-MOA precision. The testing also includes cross-platform reliability checks with a CETME rifle, demonstrating the importance of cycling and function across different firearm platforms.

Quick Summary

Affordable .308 Winchester handloads were tested in M14, M1A, and CETME rifles. A lower powder charge yielded 2642 FPS and good accuracy, while higher charges increased velocity but doubled group size. Brass inspection is crucial for safety.

Frequently Asked Questions

What was the muzzle velocity of the tested .308 Winchester handloads?

The tested .308 Winchester handloads achieved a muzzle velocity of 2642 FPS with a lower powder charge. A slightly higher charge increased velocity to approximately 2700-2800 FPS.

How did different powder charges affect accuracy in the .308 Winchester handloads?

A lower powder charge yielded good initial accuracy with tight groupings. However, increasing the powder charge doubled the group size, indicating a trade-off between velocity and precision for these specific loads.

Which rifles were used to test the .308 Winchester handloads?

The .308 Winchester handloads were tested in an M14 rifle, an M1A rifle, and a Century Arms CETME rifle to assess performance and reliability across different semi-automatic platforms.

What are the key components for testing .308 Winchester handloads?

Key components for testing .308 Winchester handloads include the rifle (M14, M1A, CETME), a Caldwell chronograph for velocity measurements, appropriate targets for accuracy assessment, and careful inspection of fired brass for pressure signs.
