swathdiver said:In mid 2012 Pietta tightened the twist on their .44 Remington revolvers from 1:30 to about 1:16.
Uberti did this on their Remington .44s in 2007 and in their 3rd Model Dragoons in 2002.
Presumably this was done to enhance the performance of the cased loads fired from conversion cylinders.
