Sebastian Samuelsson took the lead on his route together with Norway's Johannes Thingnes Bö in what became a Nordic duel.
Samuelsson shot full in the horizontal shot while Bö blocked one.
But the two were together again when it was time for the last shot, standing.
There first an official stood in the way and swept when Bö was to stand on his carpet.
After that, both Samuelsson and Bö missed two shots, but when it was time for the reserve shots, it really bothered Samuelsson who had problems with the rifle.
The first relay victory in two years
But despite that, he put his two reserve shots and went out in a lead of 16 seconds before Bö who was forced to a penalty round.
He retained that lead and secured the first Swedish relay victory in two years, ahead of Norway and Germany.
Peppe Femling started the relay with five hits in the first shot, but in the second shot many missed the snowfall.
For Femling it was two but he could still hand over to Jesper Nelin as sixth, only eight seconds behind leading Norway after a nice last lap.
- The rope went at the end of the hill and I had to dig deep.
But it was not so much time, it was good, says Femling.
France long after
Jesper Nelin quickly shot everyone down in the horizontal shooter and stood for a boom in the other, while big nations like Norway and France fought.
Emilien Jacquelin, for example, drew two penalty rounds.
Nelin switched to Martin Ponsiluoma as the third nation.
- It feels good.
I had to open damn hard to get hold of them, Fat cost a little energy.
I just wanted to get as close as possible because I know that "Ponsi" easily catches up with them.
Ponsiluoma shot just like Nelin quickly and safely and went out as number one.
In the standing shooting, things went even worse with three booms.
For France, it finished in sixth place, almost two minutes behind.
