All scoped rifle shooters should agree on at least one truth: The most challenging environmental factor affecting the shot is the wind!
The wind itself is virtually invisible. But, its effect on your surroundings can assist you in determining its speed, direction, and “value.” As the bullet is propelled through its trajectory toward your target it is “swimming” through the medium of air between you and that target. If the wind is moving (and it almost always is!) so must the projectile. By best predicting the movement of the medium of air, you can better adjust for that movement and hit your target. Additionally, having a skilled spotter who can assist with the wind calling and accurately relay the projectile’s impact (and therefore any needed scope adjustment) back to the shooter can be invaluable.
This class is intended for the Intermediate or Advanced level scoped-rifle shooter to challenge him- or herself on targets while determined the movement of air and predicting the effect it will have on the projectile, then adjusting for a likely hit. The class is also intended to expose each shooter to the spotting scope and introduce those skills important to being a good spotter.
At least successful completion up to Advanced Precision Scoped Rifle.
Many scoped rifle shooters have already proven that they can hit a target and perhaps make small groups on targets at pre-determined distances in calm conditions. But can you still hit in windy or unpredictable conditions? Come to this course and learn how!
The following are some of the topics you can expect to cover:
- When does the wind matter?
- Wind and its effects of the bullet*
- Wind direction and relative value*
- Observation of wind on nature
- Wind strata
- Wind meters
- Headwinds, Tailwinds*
- Vertical components of crosswinds*
- Atmospheric Impacts on Trajectory
- Density Altitude (DA); determination and approximation
- Critical observation of a fired shot
- Communication elements from spotter to shooter
*Of course nature is unpredictable and wind cannot be conjured or created by Sig Sauer Academy. Therefore, some topics may be discussed as theories only and not able to be replicated on the range.
- Scope, rifle, ammunition, and data combination capable of +/- 1 MOA
- Eye and ear protection
- Clothing suitable to the climate/weather
- Note taking material
- Bipod or front bag
- Shooting mat
- Shooting rear bag/sock
Nice to haves:
- Spotting scope
- Kestrel (or similar)
- Tools to adjust scopes, etc.
- Whatever snivel gear makes you happy!
Free loan of spotting scopes, rifle scopes and rifles are available (in limited quantities) at the Epping, NH location for those who may need to borrow them.
