With each match you go to you are likely to learn something each time. There is a constant evolution going on with equipment, ammo selection, etc. etc. You will make mistakes but all shooters do, this is just part of the learning process. Few sports can be this competitive and yet the person you are trying your hardest to beat will stop and offer help, advice, even loan you ammo should you run short. It says a lot about the character of the people that make this sport so successful.
