Huh, didn't know it was a controversy. Heard it on a DVD I have of the Lewis and Clark expedition. MD
The L&C Expedition took 15 "short rifles" with them to the Pacific and back.
2 burst the upper part of the barrel.
Lewis was at HF when the 1803 had to be in the prototype stage.
Lewis had a letter instructing HF to make him anything he needed.
All the rifles had spare locks and lock parts taken along.
The records show that HF made
15 more 1803s than were ordered.
There were a large number of "Contract Rifles"in stores at HF. It is possible that some of these were shortened and used by the expedition. However, these rifles were not known (SFAIK) to fail in the upper part of the barrel, 1803s were.
They would have had to make new locks for them since the locks used were somewhat "lacking" and this would have allowed more standardized parts.
We really do not know what the bore size is only that when Lewis was shot with one he knew what it was a "short rifle" by the ball size. But we have no idea what it was.
The evidence for the use of a shortened is that they were there. Period. Since they were there they must have used them.
Now I have no idea what they carried for rifles.
However, based on what I have read to date, I would vote for the 1803 prototype (remember that the effort to make an issue rifle started in 1800 with the British adoption of the Baker). Based on the manufacturing techniques of the time they had to be making or even had working prototypes at the time Lewis was there. Remember everything was done from patterns and prototypes. There were no blueprints or detailed drawings.
This said I cannot say the someone with a contract rifle with a HF lock and a shortened barrel is "wrong".
Where the controversy arises is with people with a financial interest in it being one or the other. While I lean heavily to the 1803 type. I really do not care one way or the other. Nor does anyone "know" so do research and make a decision if its important. Or flip a coin....
Having the HF records destroyed at least for the most part, during the Civil War does not help.
