Bobs' 223 Bulk Bullets - Crimp tests

Published on August 20, 2017
Duration: 16:18

This guide details a methodical approach to testing the impact of bullet crimp on .223 Remington ammunition reliability and accuracy. Expertly demonstrated by Johnny, the process involves systematically varying crimp levels using a Lee Factory Crimp Die and analyzing results for bullet setback and group dispersion. The findings indicate that for this specific load, crimp has minimal effect on performance, highlighting the importance of empirical testing for handloaders.

Quick Summary

Expert reloading analysis of .223 Bulk Bullets shows that crimp level has minimal impact on accuracy and velocity. Using Hodgdon H335 powder, Federal primers, and Lake City brass, no bullet setback was observed even with light crimps on an AR-15.

Frequently Asked Questions

What is the recommended OAL for .223 Remington reloads tested in this video?

The Overall Length (OAL) for the .223 Remington reloads tested was precisely set at 2.215 inches. This measurement is crucial for ensuring proper chambering and magazine feeding in AR-15 platforms.

How did different crimp levels affect the accuracy of .223 Remington reloads?

According to the test results, varying crimp levels had very little impact on the accuracy of the .223 Remington reloads. Group sizes remained consistent, ranging from 1.29 to 2.10 inches at 100 yards across all tested crimp settings.

Was bullet setback observed during the .223 Remington crimp test?

No bullet setback was observed during the .223 Remington crimp test, even with a light crimp or no crimp applied. The bullets remained seated at the specified OAL after firing nine rounds, indicating reliable performance.

What components were used in the .223 Remington reloads for this crimp test?

The tested .223 Remington reloads utilized Lake City brass, Federal AR Small Rifle Match primers, 25.0 grains of Hodgdon H335 powder, and 55 grain FMJBT bullets, all loaded to an OAL of 2.215 inches.
