The problem! - I think for the most part is the fact there is no standard for a bore. The/A company, even a company like TC will have variances in their bores,can cut the bore anywhere in the vicinity of the advertised diameter... even when the tooloing gets olds and dull and does not provide uniform barrels it is Ok because there is no standard... Therefor sabot manufactures need to amke a variety of different thicknesses of sabot to fit the barrel. 45 cal being the more popular bullet to be used then several different thicknesses of sabots have been developed for them.
In most instances, but certainly not all, the 44 sabots come in one universal thickness developed by each sabot company and can be a bear to get down in tight bores also.
Using TC sabots, manufactured by different companies - who ever gets the contract, can be your best bet when fighting a tight barrel. + actually shooting and using your bore will loosen it up some.
another 2 cents.... wish the keyboard had a cent symbol....
