Miller's Musket Conversion: The Trapdoor We Have At Home
This guide details the operational and mechanical aspects of the Miller Breechloading Conversion, a post-Civil War modification for the Model 1861 Musket. It covers identifying key markings, understanding the breech block, extractor, and firing pin mechanisms, and the importance of the stock channel for cartridge loading. The conversion, developed by George and William Miller, aimed to adapt percussion muskets to .58 caliber rimfire cartridges. Approximately 2,000 were produced, but military testing revealed issues like gas leakage and misfires, leading to its limited adoption.
