I am a little late getting in on this...but just some observation...
ALL of the above posts give excellent info. My club welcomes new shooters and they are usually paired with a patient SO who wants you to have fun and be SAFE.
I would suggest that you go and watch a match before you compete. You will pick up a lot just by being around it.....and....get involved. Target pasters are ALWAYS welcomed.
Talk to the people there....don't be afraid to ask any question that you may have, most will be very helpful.
I wish you good luck and Welcome To the Addicition...!!!
