Experimental .30-40 Trapdoor Springfield
This video explores an experimental variant of the classic Allin conversion Trapdoor Springfield rifle. During US magazine rifle trials in the late 1800s, the Ordnance Department rebarreled a limited number of Trapdoor Springfields to the .30-40 cartridge. These served as a baseline to compare new rifle designs against in terms of recoil, accuracy, and handling. The video features a modern reproduction of this rare experimental rifle, built from original parts, providing a unique opportunity to examine this piece of firearms history.
