doc, i am new to this also. i started shooting end of march this year, made marksman first try, sharpshooter 2nd try and hopefully expert by mach 2010. here is what i found. practice single taps, practice double taps, practice transtions, all live fire. practice draw, sight alignment and reload every night. don't get caught up in the speed chase and shoot for accuracy. also don't get caught up in the classifier but enjoy the matches.
p.s. make some of your practices long distance shooting like 25 - 30 yards. after you shoot that awhile 7 yards feels like a gimme. my 2 cents
