Note--The RD was calculated by averaging the smallest and largest diameter of each recovered projectile (ex. .47 x .87 = .67). Averages for 5 shots noted below:
9 mm Black Hills/Barnes 105 gr copper JHP
Bare: VEL = 1426 f/s, PEN = 12.9” RD = 0.62”, RW = 104.4 gr
Denim: VEL = 1417 f/s, PEN = 12.7”, RD = 0.60”, RW = 104.7 gr
Auto Glass: VEL = 1444 f/s, PEN = 13.6”, RD = 0.41”, RW = 88.6 gr

.45 ACP Taurus/Barnes 185 gr copper JHP
Bare: VEL = 921 f/s, PEN = 11.7”, RD = 0.67”, RW = 184.4 gr
Denim: VEL = 922 f/s, PEN = 11.0”, RD = 0.67”, RW = 185.8 gr
Auto Glass: VEL = 924 f/s, PEN = 13.6”, RD = 0.48”, RW = 184.6 gr

While the .45 ACP copper JHP is slightly deficient in penetration, I would not hesitate to use this load when a lower penetration projectile is desired--it is more versatile in different potential engagement scenarios and far superior compared to Triton Quickshok, Aguila IQ, Magsafe, Glaser, etc...
