This can lead to poorer accuracy, because it becomes more difficult to consistently shoot the rifle with greater recoil movement. Also, the amount the rifle recoils while the bullet is still in the barrel increases. In the #1, 1994 issue of VERY HIGH POWER we looked at how barrel stiffness decreases with length, and as a result potential accuracy possibly degrades too. There are a few drawbacks to choosing an extra long barrel, however. Adding barrel length is kind of like shifting a car into overdrive: more velocity for the same input. The other option is to use a longer barrel (having no effect on chamber pressure), utilizing more of the powder gases. One is to burn more powder, but exceeding safe pressures soon puts the brakes on that. With a given case and bullet, there are just two ways to increase The higher the velocity, the flatter the bullet will shoot, with less wind drift, more energy when it reaches the target, and an extended maximum range. This is especially true if that bullet also has a high ballistic coefficient. Barrel Lengths & Velocities for the 50 BMG Janu2:19 amīullet velocity is a very important ingredient of successful long-range shooting.
