Go to a match.....
two or three days before the match starts WITHOUT a RIFLE. You will learn more and the shooters will available to answer your questions. This might be difficult at a club match, but when you have a NBRSA/IBS sponsored match, there should be several very good shooters there. Then stand and watch, NOT the targets, watch the shooters techniques....free recoil, etc. THEN look at the crying wall and see what works.
Good luck, "Snuffy"
