In real practice, these would be quicker out of the hole, but the stability in flight would come into question as the range increases. Effective hit power will drop significantly as distance increases.
The dimpling effect on a golfball, and the threads on a baseball are designed specifically to increase their flight characteristics. Done wrong, there are very negative flight characteristics. In the world of high speed propulsion, whether flight, sailing vessels on or under water, and rolling over land- how you 'finish' is just as important as how you lead. As I can recall, there is no successful plane, sub, car, or artillery that has a gaping hole in the rear with no propulsion purpose. Once the fire is out..... the hole forms a vacuum, and the speed is literally sucked into the rear of the object. Look no further than the tail/ trunks on cars from the 50's to 70's, and contrast with vehicles from the 90's to present. The 80's was where the transition was made over entire fleets of cars rather than purely sport models.
