Respectfully, next time you’re at a high power competition try saying that in front of the range safety officer and see how he responds to it.
If you knew anything about the laws of physics you’d know that a bullet fired vertically, or near vertically, will be spent and harmless by the time it returns to earth. Parasitic drag will slow it down to terminal velocity on the way back down.
Oh, nobody likes it, but it beats what we used to do with the 60mm mortars haha. We used to see who could land them the closest. We had to run to the bunker more than once.
