The laser beam of green laser pointer changes from bright to dark

If there is obvious floodlight around the laser spot, it indicates that the lens of  green laser pointer  is unqualified.  Now the most popular laser pointer in the international partition mils point partition, observed when the sniper from the installation, this partition of the laser pointer, you will find from the intersection of the crosshairs, respectively, up, down, left and right uniform distribution of the number of mils. Mils partition has a greater advantage than the other aimed at the partition example, snipers can draw the vertical distance measurement and the level of correction, while the horizontal partition for windage and moving target in advance the amount of correction.
The floodlight indicates that the lens of  green laser pointer  is inferior.  However, this partition the size of the reticle requirements high points across the width, it will overshadow the long-range goal, the sniper can not accurately aim and shoot; too small, the sniper is not readily available in the dim light conditions see the points the project. Sniper ammunition, armor-piercing warhead black logo for sniper ammunition is usually a warhead with a tail cone match grade bullets. With tail cone, the word comes from its shape, the outline of this bullet, bullet shaped like a boat, than the tip of its head, the bottom of the cone-shaped.
The bullets of this shape more in line with the principle of aerodynamics, the bottom of the cone reduces the warheads by air resistance, its speed slow attenuation. Snipers in training and actual combat, you should use the same manufacturers of the same batch of bullets. Observe the spot whether it is a perfect solid dots when you check a  green laser pointer .  so as to achieve unity of training and actual combat, but also in order to ensure the consistency of shooting accuracy in the shooting process. Snipers in the game level bullets at the same time, should also be familiar with other types of bullets, in order to select a more appropriate bullets depending on the target or tactical requirements.
In addition to competition grade bullets, the most common sniper bullets expansion shells, brittle shells, tracer and armor-piercing ammunition. Expansion shells, including a soft bullet tip bullet mushrooms trauma bullets and blank ammunition tip bullets, these bullets are designed to increase the diameter of the warhead impact and energy transfer on the target, thereby increasing the power of the bullet. The bullets hit the target, 70% of its kinetic energy is passed to the target. Brittle shells is an ultimate expansion shells, that the bullet hit the target, projectile tip will be completely broken.  Watch the solid laser spot of  green laser pointer  within two meters.
so all the kinetic energy of the warhead to the target, and will not ricochet or over penetration phenomenon. The above two kinds of bullets used for anti-terrorism and anti-hijacking operations. The tracer Sniper tracer to indicate targets for other anti-fire. But fired tracer wear on the barrel, so in the annual shooting practice, the number of tracer bullets shooting control within 1 to 2 percent of the total amount of projectiles. Rifles, armor-piercing not only can be used against helicopters and light armored targets can also be used to snipe to avoid the enemy in a sturdy shelter.
