Most rifles that saw any use were recut (freshed), often several times. Recutting usually adds 2 calibers, a 50 becomes a 52.
This is a minor nit-pick, perhaps, but it is my understanding from reading that one could freshen the grooves a few times before it became necessary to enlarge the bore, unless the lands were severely damaged. One simply went to a thicker patch. If this was/is correct, it would moderate somewhat the anticipated rate of caliber creep.
With the groove itself acting as the guide for the cutter, this did not require a full rifling bench, and the cutter assembly could be fabricated easily by any gunsmith or skilled blacksmith, and on the spot, if need be, as was done on the expedition IIRC.
As I have nothing factual to add specifically to the '03 vs '92 Mod 1 ('92A1?) debate, I'll get back to work now. This discussion has been (largely) a quite enjoyable read.

Barrels with minor problems can be lapped (leaded), a far less aggressive treatment than freshing and only slightly changes the size.
Cutting the grooves deeper will not address the problem of loose ball fit near the breech. In patched ball rifles the grooves mean little and only need be .007-.008" deep.
Once a bore is worn past the point of being accurate through corrosion or erosion its going to take about .01" on a side to clean it and make the bore uniform. This can be put off sometimes by using a larger ball but eventually its going the need "freshed" as the ball gets too hard to load through the tighter part of the bore. This makes a 50 a 52. They generally were enlarged at the breech. I would also point out that they might be enlarged to fit a cherry the smith had on hand for a mould.
The recutting process is why rifles that saw much use always have vise tracks and wrench marked breech plugs. I would also point out that rebreeching was required at times if the threads were smaller than the groove of the barrel after being recut.
If you must believe all the early guns were big then look at rifles of Colonial America. Several rifles with very little use are featured. They have been in Britain since about the time of the American Revolution I don't think any are over 50 caliber.
A quick look at ROCA I & II will show 4 rifles is very good condition that were removed to England at the time of the revolution, one is a documented battlefield capture, one was documented to about 1800 in England but could easily date to the 1780s according to Shumway.
#44 44 caliber
#96 42 caliber
#108 45 caliber (barrel is 1.5" at the breech but heavily tapered)
# 121 47. This is a documented battlefield capture southern rifle.
There are others of 50 and under but #44 to #121 were sent to England when near new so the bores are almost certainly representative of what they were when made.
There is an early Lancaster rifle by Resor in "Steel Canvas" in near new condition that dates to 1770 or before that is 42 caliber.
However, we have documentation that some liked smaller bores and some liked wider bores. But most mentions at the time indicate the 54 was the typical large bore in Rev. War times. Yes *there were bigger bores made*. But 30-32 to the pound is often listed as a maximum.
I believe ECONOMICS restrained bore sizes.
A 54 cost about twice as much to shoot as a 44 with little real gain for most uses at the time in question.
A 62 or 66 is off the charts so to speak , a 66 uses a 1 ounce ball or very near it, the .433 ball weighs less than 1/3 an ounce.
I have no complaint with the idea that large bore rifles, over 50-52 caliber were made, its irrefutabe. But it is impossible to make blanket statements such as "early rifles averaged 53 caliber" when rifles were recut, bored smooth etc etc over the course of their lifetimes. This simply cannot be ignored.
The "1792" Contract Rifle has been been under discussion here. They were made for military service (one place a large bore is especially useful) they were apparently made as 49 caliber. There is a 1803 1st model in the Cody Firearms museum that is now 60 caliber rifled. Are we to think that some 1803s were made as 60 caliber? Its been FRESHED. Probably 2-3 times maybe 4. This rifle is 30+ years newer than most early kentuckies.
Walter Cline reamed and re-rifled or freshed original guns to make shooters of them during the early 20th century. Read his book. Along with detailing rerifling and freshing barrels he states that "Not many "Kentuckies" in original bore condition exist today" this was early 1940s. People were recutting originals to use in matches when the sport started to get more popular in the 1930s. He was thankful that some ML gunsmiths still existed at the time that knew how to fresh barrels and make repairs to get rifles shooting again.
When you see a Rev War period rifle converted to percussion you must understand that this probably took place in the late 1820s (50+ years for some rifles see rifle # at the EARLIEST and it was not done by its original owner in most cases but his son or grandson. These rifles did not fall from use in their original owners lifetime and possibly not in their grandchildrens life time if they could be made serviceable by any economically viable manner.
Freshing was a very common job for gunsmiths. We know it was done, we know how the freshing cutters were made. Kindig points out that Leonard Reedy listed the making of 48 guns while freshing 128 in 18 years.
The common dogma has been that the early rifles had large bores 54-58-62. But this was not the average size nor can it be proven that the 58-62 were all that common. But its very difficult to overcome a "fact" when its "common knowledge". Had you asked me before I started looking closer some years back I would have said they were usually 54 or bigger.
