Upfront admission - I am NOT a highpower shooter in competition, and I may well be full of crap, but, that said:

Another (gentle) tip for next time: watch some of the "stangskyting" videos on YouTube, and note that they never lose the cheek weld, and do NOT dismount the rifle either between shots (even if only a bit) OR reloading. The bolt handle is never released from the thumb and index finger, except to insert the charger, and the trigger is pulled by the middle finger. A phenominal rate of speed is obtained.

Now - it appears that their time limit is shorter than yours, and you did not lose any shots, but it still stands to reason that every second NOT performing some mechanical function, especially unnecessary ones, is a second that could be spent aiming.

Just a thought, and I wish you all the best - would certainly like to attend, but that is not in the cards.
