No, what I mean is that in the "Aliens" universe, both the M41 rifle and the service pistol shoot 10mm rounds. But the M41 round is longer and higher-velocity than the 10mm round fired by the pistols. I don't remember dimensions, but it might be that the M41 round is 10x30mm, while the pistol round is 10x20mm. But the point is, they're the same diameter, different lengths.
