Sorry, but your screenshots look vague...

As for the issue itself, the process of verifying if a bullet hits an enemy is server-based. (P2P-based?) We make the actual "hit detection area" of the bullet of Goshawk bigger than what it looks like. (About 0.5m wider) so that players can hit the target more easily. (With +0.5m margin of error)
So the actual "collision" area is wider than what it looks like from bullet trails.
