The HW98 and HW80 etc have relatively small chisel detents but they can be made as accurate as any springer, so I would say the barrel lock is a waste of time and engineering.

Get a fixed-barrel rifle if you are concerned about breech misalignment.
The Diana Mod 65 and 66 break barrels use a locking lever to collapse the spring of the detent and thus mechanically wedge the chisel edge of the detent against a small chisel like protrusion in the action, thereby eliminating having to rely on just the spring's tension to achieve a good lock-up.
No amount of abuse or slapping will make these Diana barrels budge once locked. Is it any more accurate? Maybe, maybe not.
The detent on its own whatever type it is, will not work as intended unless the breech block and pivot pin are wobble free.I have a high powered HW80 and HW90 both very accurate with (just) the simpler spring loaded chisel detent, but they get slapped just the same.
