Let’s study how the .22 WMR flight path modifications throughout a variety of widespread distances. Notice that the information will differ barely relying on the precise ammunition used, together with bullet weight, ballistic coefficient, and muzzle velocity, however we will take a look at a basic method to understanding the flight path.
Instruments and Strategies
Think about we’re utilizing a 40-grain bullet with a muzzle velocity round 1900 fps.
Vary Playing cards
When zeroed at 50 yards, the bullet could also be about an inch excessive at 25 yards, on course at 50 yards, after which begin to drop beneath the road of sight at distances additional out.
Zero level
At 100 yards, the bullet may drop round 3-4 inches. At 150 yards, the drop will increase considerably, maybe to 10-12 inches. At 200 yards, the drop would proceed to extend, simply falling past 20 inches.
The wind drift would additionally start to turn into obvious. With a 10-mph crosswind, the bullet might drift a couple of inches at 100 yards, and practically a foot at 200 yards.
These are estimates, in fact. The actual secret is to grasp that the trajectory will not be a straight line. Gravity relentlessly pulls the bullet downward, and components like air resistance and wind continually have an effect on the bullet’s path.
