The advertised expansion vel for the AB is 1800 fps and I find it curious why it expanded at 1600? In the case where it hit the bone, I can understand, but the neck shot is puzzling. Maybe, heat friction on the bullet from an MV of 3300 and an extended TOF softened the jacket?

    On Berger vs AB, I would have to agree with GG as far as the AB probably the best *all around*. The Bergers probably edge out the AB's in long range ballistic performnace and possibly accuracy. Not from experience, but from everything I've seen and read.

    I simply would not use a Berger for less than a 600 yd shot. JMO

    That would all depend on velocity. Big difference in 3300mv vs. say 2800.

    Well the chart you ran would just about been perfect then. Good guess.

    I am curious where you found the data that AB's need 1800 fps to open? I have seen them open up as designed well below this speed. Anyhow, if that is their claim, the bullet in the neck shouldn't have opened but it did quite well.

    I was hoping it would be but the advertised BC as of right now doesn't look as high as it should be.

    True, I figure 600 yds cause that's where the Berger bullet vel would be in the low 2000's.... and I'm just guessing that's where I would see more controlled expansion.
