Cant sensitivity level

1. A method of establishing a cant sensitivity level for an optical sighting system, the optical sighting system having a main optical axis extending from an ocular end to an objective end of the optical sighting system, the main optical axis being fixedly aligned with a long axis of a shooting device, the method comprising:

receiving a range measurement, the range measurement indicating a distance from the shooting device to an intended target;

establishing a cant sensitivity based, at least in part, on the range measurement;

determining, by an inclinometer, a cant of the shooting device relative to a vertical transverse axis of the main optical axis of the optical system;

activating, when the cant of the shooting device exceeds the cant sensitivity, an electronic cant indicator structured to provide an indicator signal to a user; and

deactivating the electronic cant indicator when the cant of the shooting device does not exceed the cant sensitivity.

2. The method of claim 1 , in which receiving the range measurement comprises receiving the range measurement at the optical sighting system.

3. The method of claim 1 , in which receiving the range measurement comprises receiving the range measurement at the optical sighting system from a device external to the optical sighting system through a wireless connection between the optical sighting system and the device external to the optical sighting system.

4. The method of claim 3 , in which the device external to the optical sighting system is an electronic rangefinder.

5. The method of claim 3 , in which the device external to the optical sighting system is a mobile device.

6. The method of claim 1 , in which receiving the range measurement comprises receiving the range measurement at the optical sighting system from a device external to the optical sighting system through a wired connection between the optical sighting system and the device external to the optical sighting system.

7. The method of claim 1 , in which receiving the range measurement comprises receiving the range measurement at a mobile device external to the optical sighting system.

8. The method of claim 7 , in which receiving the range measurement comprises receiving the range measurement through a wireless connection between the mobile device and an electronic rangefinder.

9. The method of claim 1 , further comprising: receiving, through a mobile application running on a mobile device external to the optical sighting system, a user input indicative of a selection that the cant sensitivity be determined automatically.

10. The method of claim 1 , further comprising: determining the range measurement by a rangefinder before receiving the range measurement.

11. The method of claim 1 , in which the inclinometer comprises an accelerometer.

12. The method of claim 1 , in which receiving the range measurement comprises receiving the range measurement at the optical sighting system from an onboard ballistic calculator.

13. A method of establishing a cant sensitivity level for an optical sighting system, the optical sighting system having a main optical axis extending from an ocular end to an objective end of the optical sighting system, the main optical axis being fixedly aligned with a long axis of a shooting device, the method comprising:

receiving a range measurement at a mobile device external to the optical sighting system, the range measurement indicating a distance from the shooting device to an intended target;

displaying the range measurement through a mobile application running on the mobile device;

receiving, through the mobile application, a user input indicative of a desired cant sensitivity;

establishing a cant sensitivity based, at least in part, on the user input;

determining, by an inclinometer, a cant of the shooting device relative to a vertical transverse axis of the main optical axis of the optical system;

activating, when the cant of the shooting device exceeds the cant sensitivity, an electronic indicator structured to provide an indicator signal to a user; and

deactivating the electronic indicator when the cant of the shooting device does not exceed the cant sensitivity.

14. The method of claim 13 , in which receiving the range measurement comprises receiving the range measurement through a wireless connection between the mobile device and an electronic rangefinder.

15. The method of claim 13 , further comprising:

determining the range measurement by an electronic rangefinder; and

transmitting the range measurement to the mobile device.

16. A method of establishing a cant sensitivity level for an optical sighting system, the optical sighting system having a main optical axis extending from an ocular end to an objective end of the optical sighting system, the main optical axis being fixedly aligned with a long axis of a shooting device, the method comprising:
