    Bullets in Flight: Understanding Rifling & Velocity Loss

    I get it now :) A bullet will maintain angular momentum as it decelerates and can increase past its original rate of twist (in distance). Twist rate is used with velocity to get a bullet to a specific rotational velocity required to stabilize in flight. Thank you, I plan to hang out on the...

    Bullets in Flight: Understanding Rifling & Velocity Loss

    Thank you for the warm welcome. This is the first time I have had to do some real thinking in a long time. It is fun. I have not defined my thoughts yet. I am reading a lot currently trying to gather facts and ideas. The main impedance of linear motion is air resistance. Rotational motion...

    Bullets in Flight: Understanding Rifling & Velocity Loss

    My apologies, I was assuming a rifled barrel with 1 rotation per 10". Quote from http://en.wikipedia.org/wiki/Rifling#cite_note-12 "Rifling is the process of making spiral grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis. This spin serves...

    Bullets in Flight: Understanding Rifling & Velocity Loss

    Is this statement correct? As a bullet flies, it loses forward velocity MUCH faster than it loses rotational velocity. If a barrel rotates a bullet 1 turn in 10 inches. Would it not exit rotating at the same rate regardless of velocity? Understanding as velocity is increased the RPM will...
