Zeroing is a very important part of preparing for a race. If you don't allow enough time to do it right, or skip it altogether, my experience has been that you're guaranteedpoor shooting performance. The following is a procedure for more advanced biathletes. Thanks to Robert Lober for providing this sheet.
1) Be completely physically warmed up when you come to the range to zero After receiving target assignment and any additional information from your trainer, go to the shooting point and shoot five fouling shots, standing, at your target
3) Assume a prone position. Dry fire. Get mentally prepared to shoot your best.
4) Before firing your first shot, estimate the wind and put on the windage. You should be able to hit the x-ring with your first shot. Your group should be centered somewhere in the x-ring. Shoot five shots for zero. Ski back to your trainer for advice.
5) Your trainer will give you any changes and other additional information at this time. If necessary, repeat step #4.
6) Confirmation. Ski on the track. Ski far and long enough so that you can come into the range and shoot your confirming shots at the same intensity (heart rate, stress level, breathing, etc) you expect to race with. Race pace confirmation of your zero is critical.
7) Shoot on the targets as you would expect to shoot during a race. That is, use all five marks shooting right to left, or whatever your technique is. Return to your trainer for additional advice.
8) Ski the first loop or as much of it as possible so that you can ski into the range at your race pace. Is this the same intensity you shot in #6? If not, you have just wasted twenty minutes and guaranteed yourself poor shooting performance...
9) Remember to dry fire standing before you call the zero process complete.
