Q&A 45: Repros, Sporterizations, and Guest Appearances by CMMG and Calico

Published on September 17, 2020
Duration: 56:16

This Q&A episode delves into the complexities of firearm reproduction, hypothetical advanced propellants, and modern firearm design choices. Discussions cover the challenges of replicating historical flintlock repeaters, the engineering behind CMMG's Banshee, and the historical development of polymer AR platforms. Expert insights are provided on the M14's accuracy limitations, the unique advantages of Calico's helical magazines for rimmed cartridges, and comparisons between the M1 Carbine and SKS.

Quick Summary

Calico's helical magazine system is uniquely suited for rimmed cartridges like .357 Magnum and .44 Magnum because it effectively avoids the 'rim lock' issues that commonly plague traditional box magazines when feeding these types of rounds.

Frequently Asked Questions

Why are Kalthoff or Lorenzoni flintlock repeater reproductions not commonly made?

Reproducing Kalthoff or Lorenzoni flintlock repeaters is difficult due to the extremely high manufacturing precision required. Additionally, there are significant liability risks associated with potential magazine explosions, making them cost-prohibitive and legally complex to produce.

What makes CMMG's Banshee suitable for .45 ACP?

The CMMG Banshee uses a radial delayed blowback operating system. This system is specifically chosen for calibers like .45 ACP to effectively manage harsh recoil and prevent excessive fouling, which can be problematic with direct impingement or straight blowback in short gas systems.

Why are Calico helical magazines good for rimmed cartridges?

Calico's helical magazine design is uniquely suited for rimmed cartridges such as .357 Magnum and .44 Magnum. This design avoids the common 'rim lock' issue that plagues traditional box magazines when feeding these types of cartridges.

Why is the M14 difficult to accurize for sniper roles?

The M14's wooden stock and its bedding requirements make it challenging to maintain consistent accuracy in the field, especially after disassembly for cleaning. This led the military to prefer purpose-built sniper rifles over modifying the M14 platform.
