This guide details the improved loading ram mechanism of the Colt 1860 New Model Army, contrasting it with the simpler system of the 1851 Navy. Expert analysis highlights the 'creeping lever's' rack-and-pinion design, which ensures consistent bullet seating and improved ballistics by providing even leverage. The explanation emphasizes the mechanical advantages over older designs, drawing on historical patents and detailed visual examination.

Quick Summary

The Colt 1860 New Model Army's 'creeping lever' loading ram, inspired by the Root pocket pistol, uses a rack-and-pinion style gear system. This design ensures even leverage, preventing bullet deformation and improving ballistic consistency for tighter groups, unlike the simpler hinge rams of older models like the 1851 Navy.

Frequently Asked Questions

What is the main advantage of the Colt 1860 New Model Army's loading ram?

The Colt 1860 New Model Army features a 'creeping lever' loading mechanism, which uses a rack-and-pinion style gear system. This design ensures even leverage throughout the loading stroke, preventing bullet deformation and leading to more consistent ballistics and tighter shooting groups compared to older, simpler hinge rams.

How does the Colt 1860's loading ram differ from the Colt 1851 Navy's?

The Colt 1860 New Model Army utilizes an advanced 'creeping lever' system with gear teeth that engage the frame for consistent leverage. In contrast, the Colt 1851 Navy and other older models employed a simpler hinge ram, which could apply uneven pressure, potentially deforming bullets and causing varied ballistics.

What historical firearm influenced the Colt 1860's improved loading ram?

The innovative design for the improved loading ram found on the Colt 1860 New Model Army actually originated from an earlier firearm: the Colt Root pocket pistol. This shows a lineage of mechanical development within Colt's manufacturing history.

What are the potential accuracy issues with older percussion revolver loading mechanisms?

Older percussion revolvers with simple hinge rams can cause uneven pressure when seating bullets. If a bullet is seated crookedly or deformed ('mushroomed') due to inconsistent pressure, it can lead to varied ballistics across the chambers and negatively impact the firearm's overall accuracy.
