So I am going to practice some target disciplines, basically just for fun with a few friends.

My question is, taking 10 metre pistol Target shooting as an example, I presume you measure 10 metres from the target to a shooting line.

So is that line something that you stand at with the pistol going over the line but you must not cross with your feet.

or does the pistol have to be behind the line and it must not go over that line in any cirumstance

Hope that is clear.
