"...The answer may exist if we can find anything definate on the gauge/caliber of the amunition carried, weren't the 1803's 52 or 53 caliber? "
________________________________
Henry Dearborn, Secretary of War at the time went into a rather lengthy description of the new rifle in his letter dated May 25th 1803 when he authorized full production of the gun.
Among the things he wrote were:
"...The Barrels of the Rifles should not exceed two feet nine inches in length and should be calculated for carrying a ball of one thirtieth of a pound weight-the barrels should be round from the muzzle to within 10 inches of the Britch and not of an unnecessary thickness especially in the round part..."
One thirtieth of a pound would be a 30 bore which equates with 233.3 grains. This is just about exactly the weight of a .535 diameter ball (give or take a few grains) which in our modern world of barrel sizing would be used in a .54 caliber bore.
As for finding out what caliber L&C's rifles were we are at a loss. There is included in the list of items only the words "15 Pairs of Bullet Moulds". No calibers were mentioned.
Regarding scholarly research, much has been done without definitive results leading to the two camps one saying the 1792 rifles while the other says 1803 rifles.
I tend to think both of them were correct with some of both rifles being taken on their journey.
As I mentioned above, this would be the only good reason for them saying "Short Rifle".
If all of the rifles were the same, whether long or short they would have been refered to only as "Rifle".
