I just started air pistol recently. I'm using a 45 year old Walther. I plan on shooting in a match at the end of February. What is a realisitic goal for the match? My goal is 510. I think I can do it. My major concern is nervousness for my first match ever in an unknown environment. I'm not concerned about not shooting astronomically high, I just don't want to embarrass myself around people who have $2,000 guns and eagle eyes.
