I've looked all over the internet and all I keep seeing is that he he got the nickname in 1861. Why was he called "Wild Bill" instead of "Wild Jimmy" or "Wild Jim"?

From Wikipedia:
While in Nebraska, Hickok was derisively referred to as "Duck Bill" (especially by business acquaintance David McCanles, and his associates).[7] He grew a mustache following the McCanles incident (see below), and in 1861 began calling himself "Wild Bill".[8][9] When later recounting his exploits to audiences, he claimed that his nickname until 1861 had been "Shanghai Bill", given to him, he said, by the Jayhawkers because of his height and slim build.[10]
'wild bruce dern' would be a better title.
