Duration: 16:48

This review focuses on the CMMG Banshee in 4.6x30mm, a rare caliber typically associated with the HK MP7. The video details ballistic comparisons with 5.7x28mm and 9mm, highlighting the 4.6x30mm's low recoil and potential for penetration. It includes range testing and experimental armor penetration tests using Kevlar and a non-Newtonian fluid vest.

Quick Summary

The CMMG Banshee in 4.6x30mm offers extremely low recoil and high controllability, making it very manageable even during rapid fire. While both 4.6x30mm and 5.7x28mm use 40-grain bullets at similar speeds, the 4.6x30mm's smaller cross-section theoretically aids penetration.

Frequently Asked Questions

What is the CMMG Banshee in 4.6x30mm?

The CMMG Banshee in 4.6x30mm is a rare civilian-accessible firearm chambered in a caliber typically exclusive to the HK MP7. It offers low recoil and high controllability, making it an interesting option for shooters.

How does the 4.6x30mm caliber compare to 5.7x28mm?

Both calibers use 40-grain bullets and similar velocities (1900-2000 fps). However, the 4.6x30mm has a smaller cross-sectional area, which theoretically aids in penetration compared to the 5.7x28mm.

Did the Oobleck vest stop the 4.6x30mm rounds?

No, the experimental Oobleck vest failed to stop the 4.6x30mm rounds. The high velocity of the rounds proved too much for the non-Newtonian fluid to effectively dissipate the energy, allowing the bullets to pass through.

What was the recoil like when shooting the 4.6x30mm Banshee?

The recoil from the 4.6x30mm Banshee was described as extremely low. This, combined with high controllability, makes the firearm very manageable, even during rapid firing sequences.
