Swift A-Frame Velocity Range
What's the bottom end of A-Frame expansion velocity range? I'm looking specifically at .323 caliber, but I'm curious in general, also.
That 30 caliber premium hunting bullet comparison chart that was popular some time back showed the A-Frame starting it's best expansion at 2,500 fps.
Throughout the velocity range (up to 3200 fps) it maintained 95% weight retention and simply mushroomed more. Penetration ranged from 19" to 25" in that same velocity range.
I wish I could find that chart online to reference............
