Barrel length?
Does barrel length make a huge difference when reloading? I have a Ar 15 with a 16" bull barrel. 1X9 twist. I am trying to figure out the perfect load, but I was wondering if I should be using a faster burning powder since it is a shorter barrel??? does this make any sense??

I believe barrel length in a AR has more to do with bullet speed. If you listed the powder and bullets your shooting this could help someone to recommend a powder for accuracy. You might look here for lots of info and Sierra’s loading data which lists accuracy loads for different weight bullets -

About the only difference the use of a faster-burning powder would make in a short barrel is the amount of muzzle flash.
Generally, barrel length affects velocity, but not group size. Longer barrel = faster bullet. The longer barrel allows one to take advantage of the pressure curve with slower-burning powders, that extra micro-second of acceleration given to the bullet. |

The rule is that the loads that give the highest velocities in long barrels also give the highest velocities in shorter barrels.
