I'm gonna poke some holes in your theory.
Starting in 1869 with the American Model, ALL S&W Top Break revolvers had 1 7/16" long cylinders. These were a suitable length for the 44 S&W American and 44 Russian ammunition. Both of these models had the extended gas bushing pressed onto the cylinder that prevented fouling from being blasted out of the barrel/cylinder gap and onto the cylinder arbor.

Schofield Model
New Model Number Three
44 Double Action.
They all had a bushing with this sort of arrangement in relation to the barrel/cylinder gap. This photo shows the relationship between the front of the bushing on a Schofield and the barrel/cylinder gap. There was nothing new about this, S&W had been doing it since the American model back in 1870. There was nothing shortened about the Schofield cylinder in relationship to the barrel/cylinder gap, the arrangement of a 1 7/16" long cylinder with S&W #3 Top Breaks had always been that way.
S&W simply did not want to interrupt the manufacture of over 150,000 Russian models to make up new tooling for a longer cylinder and frame for the 45 Colt. Bear in mind, S&W made over 150,000 Russian models, but less than 9,000 Schofields. Why in the world would they jeopardize the profitable contracts they had with the Russians, Turks, and Japanese for an Army contract they were not at all sure they would win?
You are correct, the original 45 Colt cartridge held about 40 grains of Black Powder, and the malleable iron cylinders did blow up on occasion. And the charge was later reduced to 30 grains.
But according to Jerry Kuhnhausen in his book The Colt Single Action Revolvers, a Shop Manual, Volumes 1&2, Colt did not begin making frames and cylinders from low-medium carbon steels until mid 1883. Long after the question of what type of cartridge should the new S&W Top Breaks be chambered for had been answered for the 1875 contracts with S&W.
As for the wrong ammo being sent to the wrong units, I have heard speculation about that for years.
I have never seen documentations that it ever actually happened.

Great info in all your comments. I get about 30-35 shots out of my 5 inch uberti schofield when using 45 schofield brass, 250gr bp lubed bullet, 24gr of 3f black powder(I’ve used schutzen and goex) the schutzen seems to burn a little bit cleaner. With 45 Colt brass, the same lubed bullet and 30gr of 3f(my load I used in my saa, clones and conversion clones, and Cimarron/uberti 1866 carbine) I get maybe 10-15. I’d like to try the even shorter 45 cowboy special brass one day if it’s ever made again and figured out how to reload it with no dedicated dies available. Also, my loads mentioned above all use a vegetable fiber wad over the powder. I plan on getting one of cimarron’s new model 3 first model Americans they released in the last year or so when an 8” 44 special model becomes. When I can find the brass I want to try it with 44 Russian black powder loads. That brass is near impossible to find as well. Sad that we can’t shoot them the historically accurate way we want to. I can’t afford originals and wouldn’t want to wear them out anyway.
Lastly, are there any good gun Smiths or machinists that have attempted to modify these reproductions to add the bushing on the cylinders and modify whatever else to make them work or even a whole new cylinder? Is it even possible?
