It's already using a Cinematic ramjet to get to 0.5 c. A realistic speed limit is probably a good bit lower than that. Like magsails ramjets appear to make better brakes than accelerators.
Ramscoops are thought to be better brakes than anything else at almost any speed, if I recall. I would consider them super science just as much as reactionless thrusters, but that's just my personal opinion. Comes down to flavor.

Not to mention the difficulty in actually hitting a planet sized target at 0.5c, let alone any number of nines. You can't line it up perfectly at the start, and terminal corrections at relativistic speeds are gonna be hard.
