"13 Km is quite much, yeah, but we can't compare 13Km to 100 sword lengths because we don't know what a sword length is to begin with." A wakizashi is between 30 and 60 centimetres (12 and 24 in), with an average of 50 cm (20 in). 13km is equal to 1,300 000 centimeters (511,811.024 inches So basically it can go 260,000cm (25,590. 5512 inches) times as far as Shinso.

Also Ichigo was bleeding; and I doubt this happened spontaneously so..yes Gin managed to wound him.
