Heavy Nerf Cannons have significant advantages, but, like all Nerf guns, they have drawbacks as well:
- Limited range when compared to other Nerf guns
- Often-questionable accuracy
- Enormous reload time
- Difficulty of modification
Since modified Nerf guns such as the Nerf Titan and SM5K can consistently shoot over 200 feet, it is inadvisable to neglect longer-ranged weapons.
