The longer the bore the further it shall travel because it has more time to spin and pick up speed in the barrel. as in rifles the bullet spins and get more speed so it'll go farther

Melvin Watts · Answer 2

OK think of it distance, The smaller the distance less momentum is needed the Longer the distance the the longer the momentum is needed.

And The Answer Is quite easy their was no reason to be asked

Answer:1.0meter
