    is a 20" bull barrel as accurate as a 24" bull barrel in a bolt action 308 cal rifle

    For the most part, yes.

    Barrel length has little to do with accuracy.

    In most cases it will be more accurate. A shorter barrel is stiffer than a longer one and will yield better accuracy.

    At the distances the majority of shooters will ever even try, Yes.

    the conventional wisdom is that at longer ranges (beyound 600) a 20" barrel can or will suffer slightly against 24-26" barrels due to the gains in MV from the longer barrels allowing the bullet to stay supersonic a little bit longer.

    I watched Todd Hodnett shoot a man sized steel target with a 20" .308 at 1 mile in person.He teaches others to do it too(great instructor). Check out "Magpul: The Art of the Precision Rifle" video. I believe one of the Magpul guys was using a 20" AR style in .308 (may have been a LaRue Predator, but don't quote me on the rifle type).

    A 20" barrel might well be MORE accurate than a 24" at moderate ranges.
    It is effectively stiffer.
    The difference is great enough that benchrest rifles for 100-300 yards usually have rather short barrels.
    The difference is not great enough to show up in off the shelf rifles, but the point is that it won't hurt.

    I consider true long range shooting with such a short barrel to be a stunt, possible for a good shot with good equipment, but not something you see done when score is kept.

    One of my shooting buddies, uses a 20" barrel 243 for his competitions(usually <800 but have seen him take first at 1000). The "pros" were poking fun of a .243, I think they all ate crow that day. He has built competition rifles,bolt and semi, for 12 years. He was the one that first got me using a 20" setup. I constantly shoot my 20" barreled .308 at 800 and less on steel. While I am not the shot my friend is, I love 20". The loss of velocity was minimal (usually less than 100fps). The twist is more important in my opinion between a 20" and 24" barrel, please know this is just my opinion. I am not doubting anyone, this is just from my experience.
