Your assessment should be right ,, on charges . You should be able to go as low as 25 grains though . And normally the top for the traditions recommendations is 100 -110 ball park

Projectiles would be 50 cal or if RB . 490 or .495. Depending on the actual bore size patches would be .010-.018
as to if it will shoot sabots well . that will depend on the rate of twist . it should be marked on your barrel with a 1 in 48 or 1 in 60

If the rifle is stock and nothings changed then your caps will be #11.

As for the loading Manual . Like CVA the traditions manuals are not to gun specific so basically you will have the same manual as a traditions hawkens , Kentucky , Pennsylvania so on and so forth .
I would shout an email to traditions and ask for one .
If your new to muzzleloading then IMO you would be far better served by getting on E-bay and buying one of the old Sam Fedella loading manuals.. Most are just on basics . However there are a couple that are full 75% load data
