Germany's Schempp was originally thought to have edged out Italian Hofer by 0.3 seconds to take the victory in Antholz, the first of his career.
But while Schempp was still left toasting the milestone, he was joined on the top step of the podium by Hofer with the pair given the same time of 14:07.30 minutes.
Despite leading early on, Schempp's compatriot Arnd Peiffer shot clean to finish third, 4.3 seconds further back.

The Frenchman now has 502 points to his name and is 89 ahead of Svendsen while Austrian Landertinger – who just missed out on the podium in fourth – is third on 331.
