Uberti 1873 .44-40 bore anomalies?

[Oregon Bill]

Sooo, I was just looking at Uberti twist, land and groove dimensions for their 1873s in .44-40 and encountered two wildly different sets of specifications.
Dixie says their Uberti 73s have a 1:36 twist, .004"-deep rifling and land diameters of ..424 and groove of .432.
Cimarron in their Uberti chart lists the following for .44-40 rifles: 1:20 twist, .4215 land and .429 groove.
Is Dixie all wet, or does Uberti make two different .44-40 barrels for their Model 1873s? This does not make sense.

Quiet here, but at least my question has been glanced at 62 times. One must keep hope alive.

Seems like I've seen people griping about Uberti's twist rate in the 44-40 a few times over the years, don't remember any details, but I think it was on this site.

My 25 year old 1873 SpaghettiChester (Uberti) has a .429 groove diameter. I am sure I checked the twist rate BUT that was two decades ago. I can tell you that it is accurate out to 200 meters with 240 - 250 grain bullets and Reloder 7.

Thank you gentlemen. More data points are a good thing.
