Actually this is the old ipsc starting position. "Stock touching competitor at hip level, rifle parallel to the ground"
In 2012 it was revised to only stock touching competitor at hip level. So by the rules you can now start with the stock at hip level, muzzle pointing up.
I think the parallel thing is a local safety rule at the Hungarian rifle range, where you're not allowed to point the barrel over the berm at any time. It's still being decided for the ERC, if it's going to be for the entire match, or just some of the stages.
We're not used to it in the nordics. If you're DQed as soon as your muzzle is pointing over the berm at any time during COF it's going to be a major concern, so we're just trying to practice for it just to be sure.
