GUIDE CALIBRATION RING

calibration ring or "gage ring" in English used to verify the calibration of refill matrices.

A calibration ring is a part that is generally used to verify that a die is producing ammunition with dimensions within the correct specifications. This is important to ensure that reloaded ammunition fits correctly in the firearm's chamber and functions safely and effectively.

The general process involves the following:

1. The calibration ring is a device of metal or other durable material that is accurately dimensioned to the standard specifications of the caliber of ammunition being reloaded.

2. After reloading some ammunition, a cartridge is taken from production and inserted into the calibration ring.

3. If the cartridge passes smoothly through the calibration ring with no problems, this indicates that the reload matrix is ​​correctly calibrated and producing ammunition within specifications.

4. If the cartridge does not pass the calibration ring or encounters resistance, this could indicate that the reload die needs adjustment or maintenance to ensure the ammunition dimensions are correct.

The use of a calibration ring is an important verification step for ammunition reloaders as it helps to ensure the quality and safety of the ammunition produced. Be sure to follow the reload die and calibration ring manufacturer's instructions to ensure your ammunition is within the correct specifications.
