I've been consuming everything I can find about the Corps of Discovery of late, and like everybody else, have my own theory on what rifles were used. I am in the unmodified (locks and slings excepted) 1792 camp, though not strongly.
The line of discussion I'd like to open up is regarding the shortened (from 42" to 33-36") and rebored to ~.54 1792 rifles. Although I find several sources that indicate these modified rifles were indeed the ones that went on the mission, I find little to back up this assertion. As near as I can tell, the justifications for this line of reasoning are threefold:
1) The journals often referenced "short rifles;"
2) Capt. Lewis anticipated that the handling characteristics of the shortened rifles would be more suitable to use while embarked in the canoes/pirogues;
3) The .54 caliber would be more appropriate to Western game.
2.) and 3.) don't strike me as compelling. I expect the soldier of the day was well-used to the handling characteristics of a longrifle or lengthy musket. The idea of a heavier caliber sounds like hindsight to me. The .49 was no doubt considered adequate for anti-personnel use, which seems to have been the first priority.
To my mind, one interesting piece of evidence in favor of the shortened rifles are the drawings of Sgt. Gass. To my eye, the rifles he drew look far shorter than I would imagine a 42"-barreled rifle would. That's far, far from definitive, though.
On the other hand, one or two authors I've read imply that the unmodified 1792 rifles could have been called "short" simply because they were short relative to the muskets and other Pennsylvania rifles.
I realize we're not going to settle this, but I'd still like to hear your thoughts.
Best,
Dan
