We might be able to give you a ballpark figure highwayman, but it depends greatly on the powder being used. For example, Triple Seven will be significantly higher than Pyrodex RS, and GOEX will be lower.

 I set up my chrony with my M-L a few years ago. I got a very steady 1950 fps with a 250 grn SST out of my 50 cal Knight Disc, 26" barrel. My charge was 120 grains of Blackhorn 209 powder. Shocky's Gold powder was tested too, by my buddy. With the same charge weight & bullet he was down near 1450 fps with wild FPS swings.  As mentioned, powder type matters a lot.

The TC Owner's Manual should give you a ballpark figure with different powder charges and bullets weights. Google the inline and modern muzzle loader forums and lots of info is available there. I just started with a new TC Impact 12/12 and had learned a ton of info and data fron 5-6 torums I googled.Lots of load/accuarcy and velocity posts out there from shooters with cronys.
