I agree with all except the last one.

Higher BC bullets does not mean you'll get better accuracy. Bullet accuracy's determined by two or three things; how uniform its weight and shape is and how well balanced they are. If all leave the muzzle at the same speed and muzzle axis angle and there's no external forces applied to them, they'll all go in the same hole.

    True. But, external forces exist. So unless it's dead calm, high bc will win out over low bc at long range with all else equal. e.g. bullet uniformity/balance, shooter ability.

    Also as LouBoyd stated, the low bc bullet will become transonic sooner than the high bc bullet (assuming equal mv). Plus, better transonic stability isn't going to improve accuracy relative to a bullet that doesn't become transonic.

    So, bc rules for LRH. Nonetheless it's fair to ask, what if you could have your cake and eat it too?

    However the odd bullet that bites the dust has lead me to search for a better bullet to make it to the target more consistently.
    Ill be interested as well. I'm building a short barrel .308. Key is getting the bullets to stabilize out of the shorter tube.

    This bullet is very new and isn't in the system just yet. It will be available thru the Berger store and other re-sellers soon.

    It's easy. Use a fast twist.

    If all bullets left at the same speed and there were no external forces appled to them shooting competition would be very boring.

    I was only talking about supersonic VLDs versus transonic non VLDs at long range. I suppose there are cases where a transonic non VLDs could have lower time of flight giving less vertical stringing and lower lag time giving less wind deflection. It would have to have a higher muzzle velocity.

    Do you ever choose to shoot bullets which will be transonic at the target?
