Make sure you learn the rules and do not make too many mistakes. You will make some. No big deal.
There are no fault lines, it is all about line of sight and being 50% being cover from the point of view of the target you are engaging in tactical order.
Listen to the instructions. Rehearse in your head. You can only use your imagination. There is no shadow run. No aligning the sights and dry firing at LAMR.
Do not drop a magazine with ammo in it. If in Vickers, triple some of the targets to make sure you get a 0 and this way you can drop the magazine, otherwise you have to do a retention reload. Remember that what I described is illegal but hard to rule upon (unless you shoot 5 times on the last target).
And never move with an empty gun.
Otherwise, have fun. IDPA is low count and goes fast because nobody shadow runs or rehearses. You can be done with a well squadded 4-stage IDPA in 90 minutes, go home and enjoy the rest of your weekend.
I have been reading them over and over and over. TONS of rules, some kinda dumb but hey, that's the game. I will be attending a first time shooters meeting before the match and I am sure they will let us know the basics.
How is it illegal to triple targets in Vickers? Thought you were allowed as many as you want...
"In Vickers Count, which is the typical method used, the Shooter may fire as many rounds as they feel are necessary to get good hits on any given target. The only limit is the amount of ammunition that the Shooter has handy. Regardless of the number of hits on a target, normally only the best two count for score."- Racine IDPA New Shooter Brochure
