the meplat (reducing its area) involves pressing the bullets into a special die. This decreases the size of the meplat which increases the ballistic coefficient, which reduces drag, time of flight, and wind drift of the bullet. Some target shooters sort their bullets by weight, point their bullets,

If the meplats on a group of bullets are uneven, the trajectory of the bullets will vary which will cause the bullets to strike the target at different vertical locations. Bullets of the same mass that have similar-shaped meplats will travel through the air in nearly identical fashion, making it

the meplat (cutting the tip of the bullet, thus increasing its area) decreases the bullet's ballistic coefficient, increasing drag, and making it more susceptible to wind drift. So even though the grouping will be tighter, the time of flight and wind drift will be slightly greater.

The meplat plays an important role in the loading of weapons whose ammunition is guided into the chamber by a mechanism (e.g., 35:. The shape of the meplat is important in determining how the bullet moves through the air. In particular the size and shape of the meplat has a significant effect on the 288:
