The 28-year-old Tandrevold had to enter the standing shooting range with one hand over the rifle and could only support herself with one hand.
The rifle fell off in the last curve. The sling fell off and then I had to carry the rifle into the shooting range. I'm quite impressed that I got four hits, she says.
The rules state that the rifle barrel must point straight up in the air, but in the last meters before the shooting range, it pointed rather straight forward when she had to carry it.
There was speculation that Tandrevold would be disqualified, but later came the message that she avoided punishment.
I don't feel like I've done anything wrong. I shot with the rifle I had and I didn't gain anything from it. I'm far behind and have obviously lost a lot in the standing shooting range, she says.
After the shooting, Tandrevold got a new rifle.
The Norwegian finished in 23rd place in the competition.
