Cup Cadence: sight picture, trigger control, break shot clean, open breech, watch bullet into backstop, note conditions at shot, clear breech, bore pig and push, swab chamber, reload, read condition, set sights, sight picture, trigger control, break shot clean x 14. The read it, set it, shoot it, is where the art form plays a role and the only way I know to learn how to do this is to shoot in competition. Practice is more load and technique evaluation by comparison, shooting in competition is where it all has to come together. Competition is also where it counts.
Oh and yes dbm, we call it pair firing. Two shooters firing alternately at same target, unlimited sighters and ten for score in 63 minutes feels like enough time to take a nap compared to Cup shooting. This works really well IF both shooters share last shot sight settings and both rifles have the same dead wind zero. Each shooter keeps the other shooters score card. Pair firing works too well in fact in some minds. However, if in the prep period both shooters set their gear up for first shot and leave the rifle and ammo on the spotter/scorers mat set up alternate firing can come off fairly quickly because the second shooter essentially has very close to the correct sight setting for sighter shot #1. Especially of the spotter works off of his own shooting mat. This is also where target service is so, so critical. Frequently the following shot is a mere seconds into the back stop after the previous shot. If the pullers snooze you loose.
