In this video we are going to talk about the fundamentals of Biathlon sight alignment including what you should see when you look through the sights, and why this aspect of shooting is so important.
Part 1. Parts of Sight Alignment
Part 2. Sight Picture
Part 3. Importance of Good Sight Alignment
Part 4. Sight Alignment vs. Aiming
Part 5. Too little light
Part 5. Front Aperture
Calculations for poor sight alignment:
Rear sight to front sight (leg B1): 685.8mm
Off by 1mm (Leg A1)= .0835 degrees difference
Distance from front sight to Target (leg B2): 50 meters (50,000mm)
Miss on target (Leg A2)= 72.87

Great video! Thanks for putting in the effort. I'm a new biathlete and this helped a lot.
These videos are very entertaining and informative for me. I just began to follow IBU Biathlon in 2020. I have attempted to discern the rules, practices, and nuances of the sport. This channel is helpful in understanding additional details about biathlon and the most prominent biathletes. Thank you for sharing your expertise and perspectives.
Thank you for this tutorial! I hope your channel grows!
Thank you so much!
Nice job on this Brian!! Thanks
Hello Brian, excellent video and explanation re: sight alignment ! Brian Wing RSO Canmore Nordic Centre
Glad you enjoyed it! Hope to come up to Canmore again soon!
This was a great learning
Don't know if you found a mfg for sight insert but any PCM photochemical machining company can make them in what ever design you wish, currently micron level details are achieved in 1mm thick stock. Sheets can be made very cheaply
4:50 Folks don't adjust your screens (or your eyes). If you think the sights are badly misaligned here, they are!
great video! I purchased an Anschutz and even though my sights were aligned, bullet impact was way off target (>50 clicks). it turns out I need to install a riser of 12 mm (rear only). would be great if you could discuss the use of risers and why they/how they should be used. PS. my coach told me to keep the outer ring of light about as thick as the front aperture black ring and to make sure you have an even white circle around you front aperture and that works well for me.
I will absolutely do a riser video. Just make sure if you add a rear riser you add a front riser too. Otherwise your rifle will be shooting into the sky. Regardless, risers should be used more for getting good relaxed position, less about getting aim. If you are adding risers to try and move your groups I would discourage that. If your face is way to close to the sight and you don't want adjust the butt-plate anymore, then raise that sucker up!
Being off by a ton of clicks is actually common for brand new rifles, so don't worry. What direction were you off (like low, high, etc.)?
I love that suggestion from your coach. I 100% agree with that. Every athlete will figure out what works best for them but that is a great place to start! What program are you in?
Great video, thank you! Would you say that most athletes keep a 1 to 2in distance between rear sight and their eyes? To have a sight picture as shown at 1:45, my eye is about 5.5in away from the back sight, and I feel it's way too far and it is not helping with focusing on the target. Is there anything that I can do to bring the back sight closer to my eyes and keep good sight picture? I using an Anschutz rifle with Anschutz sights.
I can help with the manufacture of apertures
Hello Brian, you say one thing in this video that I believe is incorrect: 1 mm off in the sight picture corresponds to 7.26 mm (=0.726 cm). But 0.7 cm is only a fraction of the diameter of the prone target, which is 4.5 cm, and far less than the distance out to the 1-ring on a scoring bull.
Hey Scott. I just did the calculations again and even measured the distance between my sights to get an accurate number. I got about 76mm (7.6cm) as the difference.
Wondering what you calculated at the critical angle?
This could be good video content :)
@@BrianHalligan-USA What Scott is saying , you say, '7.26mm' instead of 7.26cm in the video ua-cam.com/video/5WynZCHxlrc/v-deo.html ( might want to add a caption to the video that you meant 7.26cm)
I was just talking about this with our kids program at EABC on the range yesterday - to simplify we used round numbers. We agreed that the distance between the rear sight and fore sight is between 50 cm and 1 m. With the target 50m away, the consequences of poor sight picture are multiplied by a factor of 50 (50m / 1m) to 100 (50m / 50cm), putting a 1 mm misalignment in the 5-10 cm range downrange. We all agreed that small errors in sight picture translated to big misses.
How many hours a week do elite/pro level biathletes spend on shooting? They must be able to hit those targets in their sleep with a low heart rate and time.
The training varies, obviously but I would guess a W.C. athlete shoots 400-500 rounds a week. Equating to maybe 5-6 hours per week. But. if you include the amount of time they dry fire, work on shooting position, and other rifle related sessions it's probably closer to 15 hours a week related to the rifle. Then you throw 20-30 hours of ski training on top, 10-15 hours of stretching and maintenance... Being a World Cup athlete is a full time job.
Biathlon is unique in that the clock is a always ticking. So time is always a factor. But yes, Athletes will test their untimed precision with scored shooting tests. one of the more popular tests is the 30/30 (30 shots prone, 30 shots standing) on a scoring target where perfect center is 10pts and the prone ring is 8pts. I haven't talked with any athletes specifically about their scores but I'm betting that a really good shooter is up over 550 where as a majority of the World Cup is probably around 500pts out of 600.
Hey Brian, we were at a clinic, last week and engaged in a HUGE debate on attack on the target in standing position. Real disagreement: "attack from 6 o'clock.." "No, you attack from 11, 12, 1,...o'clock..." How do u teach that? Btw, I am in Duluth biathlon.
I actually get this question a lot (Guess it's time to make a video about it 😅)
My philosophy: assuming you are a right handed shooter, when you set up into standing position, the rifle naturally wants to fall away from your body down to the 4:30-5:00 position. if you just completely let your muscles relax the rifle will fall down and away. So when shooting, I believe you should try to counterbalance that force and approach from 4:30. No matter what direction you approach you will be feeling some natural tug from 4:30 direction so the theory is approaching from that direction will really smooth out the approach. for lefties it's probably 7:30.
Bottom line: consistency is most important. Whatever you do, do it all the time so you can better anticipate the approach to the target.
When shooting at 50 meters, do the biatlon athletes have magnification on their rear sites?
Nope. Iron sights only
