Depends on which one.
No.
Endless is a strong word, but probably, at least until you figure out what works in your rifle and for you.
There is a certain learning curve associated with MLs that you will have to overcome to be successful and safe. There's also a bit more maintenance associated with them, and shortcutting that will leave you with a damaged or ruined rifle and may cost you opportunities in the field. You may find that you like muzzleloading well enough to give up something else.
