OK it's time to get real, for the cost it is an entery level gun.
Not everyone can start at the top. I have several custom made flinters with Getz, and Bobby Hoyt ,and green mountain barrels !
But with the right load and some lock tuning I can get 1 1/4 inch groups with my 2 traditions flint locks rifles at 50 & under 2 @100 yrds ,poor locks but good barrels 1-66 and very bad trigger on my Kentucky. I had more trouble with my great plains rifle's lock . I get near 95% with the traditions after my tuning almost as relable as my siler locks (tuned by Brad of cabincreek)

If you can go to muzzleloader shop like Dixons(just over the hill from me) or the Log cabin ohio .
Go to trad shoot and see what fits you and your buget . That way you might find a good used starter gun (and maybe the load it likes)
Most gun /sporting goods stores don't have a flint/muzzle loader guy
The above photos show what a good load in a starter rifle can be 50yrds low hole from clean barrel the others no wipe . at 100 clean off to right low throw out the flinch the other are 1 1/2 . the load of the other high and right are with a tighter patch .020 vs .018 but did not group as well.
Are there better flint lock rifles YES, but if you have one you can make it shoot and enjoy it.
It's more the guy then the gun.
