5.7 vs 22 Mag: Almost Didn’t Believe It

Published on March 22, 2024
Duration: 12:05

This video provides a detailed, experimental comparison between the 5.7x28mm and .22 WMR calibers, utilizing professional equipment like the Garmin Xero C1 Pro chronograph and Clear Ballistics gel. The host methodically tests penetration through various materials including lumber, plywood, sand, concrete, and steel, alongside terminal performance in gel. The 5.7x28mm generally demonstrated superior penetration and energy transfer, though both calibers showed significant tumbling effects in gel.

Quick Summary

The 5.7x28mm caliber demonstrated superior performance over .22 WMR in penetration tests against lumber, concrete, and steel. While both calibers exhibited significant tumbling in ballistic gel, the 5.7x28mm achieved greater penetration depth, indicating higher overall energy transfer and effectiveness in terminal ballistics scenarios.

Frequently Asked Questions

How does the 5.7x28mm compare to .22 WMR in terms of velocity and energy?

The 5.7x28mm, using a 40gr FMJ round from a 5.2-inch barrel, averaged 1738 FPS with 268 ft/lbs of energy. The .22 WMR, with a 40gr FMJ from a 5-inch barrel, averaged 1454 FPS with 188 ft/lbs of energy.

What were the penetration results for 5.7x28mm and .22 WMR against different materials?

In tests, 5.7x28mm penetrated 6x6 lumber and 3/4" plywood, while .22 WMR did not penetrate the lumber. 5.7x28mm also punched through 1/8" mild steel, whereas .22 WMR only dented it. Both struggled with a 6-inch sand box.

How did the 5.7x28mm and .22 WMR perform in ballistic gel testing?

Both calibers showed significant tumbling in ballistic gel, creating large wound channels. The 5.7x28mm completely penetrated the gel block, while the .22 WMR stopped at 15 inches, indicating better overall energy transfer for the 5.7mm.

What equipment was used for the ballistics testing in the video?

The video utilized professional equipment for its tests, including a Garmin Xero C1 Pro Chronograph for velocity measurements and Clear Ballistics gel blocks for terminal performance analysis, ensuring accurate and repeatable data.
