Powrball is not "specialty ammunition designed for a narrow range of performance conditions"
It is actually designed for the all manner of conditions.
4-inches penetration after passing through automotive sheetmetal - see: http://www.thegunzone.com/powrball.html
Also: http://www.m4carbine.net/showthread.php?t=26717:
9 mm Corbon 100 gr +P PowerBall 1555 f/s from G17
BG: pen=10.9”, RD=0.60”, RW=93.9gr
4LD: pen=11.4”, RD=0.58”, RW=97.5gr
The mighty 4.7” of pen after the auto windshield was not comforting…
.40 S&W Corbon 135 gr Powerball from S&W 4006
BG: vel=1362 f/s, pen=11.6”, RD=0.65”, RW=131.4gr
4LD: vel=1359 f/s, pen=12.1”, RD=0.65”, RW=131.9gr
auto windshield: vel=1365 f/s, pen=7.9”, RD=0.61”, RW=103.6gr
.45 ACP Corbon 165 gr +P Powerball from 1911
BG: vel=1230 f/s, pen=12.1”, RD=0.70”, RW=158.8gr
4LD: vel=1267 f/s, pen=11.8”, RD=0.66”, RW=159.7gr
auto windshield: vel=1251 f/s, pen=5.5”, RD=0.73”, RW=143.5gr
The frequent core-jacket separations and rounded leading edges of the PB
loads are a concern, as is their poor terminal performance after intermediate
barrier penetration. We were frankly unimpressed with these loads. If you
have to use Corbon handgun loads, stick with their DPX loadings of the
superb Barnes XPB all copper bullets.
