Method for calibrating firearm firing accuracy

Abstract

A method for calibrating firearm firing accuracy, comprises the following steps: preparing an impact point distribution detection ring which is a circular ring with an inner circle diameter of 120-180mm; preparing a firearm calibrating device, preparing a chest ring target or a firearm calibrating target, and preparing a plurality of trial fire bullets; enabling a firearm trial fire shooter to usea firearm to be calibrated and simultaneously adopt the trial fire bullets to collimate a bullseye of the chest ring target or the firearm calibrating target, and firing more than four rounds of bullets to the bullseye of the chest ring target or the firearm calibrating target; and after firing is completed, observing an impact point distribution area on the chest ring target or the firearm calibrating target, if the impact point distribution area is deviated from the bullseye of the chest ring target or the bullseye of the firearm calibrating target, adopting the impact point distribution detection ring to sleeve the impact points of at least three rounds of the bullets, and then taking the circle center of the impact point distribution detection ring on the chest ring target or the firearm calibrating target as a center point of the impact point distribution area. The invention aims to provide the method for calibrating firearm firing accuracy which is suitable for various firearmsand capable of substantially improving the work efficiency of firearm calibration and has high firing precision of calibrated firearm.

Description

technical field [0001] The invention relates to a method for correcting the shooting accuracy of a firearm. Background technique [0002] Correcting the shooting accuracy of firearms is referred to as calibration gun, also known as shooting effect correction. Calibration gun refers to the process of correcting the gun aiming at the baseline with the shooting accuracy of (approximately) standard conditions. The purpose is to keep the sight in an accurate state. Gun calibration is usually performed before the first use of a new gun, after replacing or repairing parts that affect shooting accuracy, or when abnormal shooting accuracy is found during use. Existing fire effect correction usually uses a calibrator, which needs to be inserted at the muzzle of the gun when in use. However, the existing gun calibration method needs to shoot to determine the direction of deviation, adjust the sight, shoot again to determine the direction of deviation, adjust the sight again, shoot ag...

AI Technical Summary

Problems solved by technology

However, the existing gun calibration method needs to shoot to determine the direction of deviation, adjust the sight, shoot again to determine the direction of deviation, adjust the sight again, shoot again to determine the direction of deviation, and then adjust the sight repeatedly to complete the calibration of the firearm. The efficiency is low, and it is very dependent on the work experience of the corrector to complete the correction work

In addition, the existing calibrating devices are all special-purpose and can only be used for a certain type of firearms, and cannot be used for multiple firearms
